Monster girl assault!
A downloadable game for Windows and Android
About the Game
You are the king of the last human city, and your task is to protect it from an invasion of mysterious and enchanting, yet highly dangerous, monster girls.
How to do it?
You must build a strategic defense, balancing different types of soldiers to safeguard the final stronghold of humanity.
Game Story
Long ago, there was a kingdom where life flowed peacefully. Some residents headed to gyms after a hard day's work to grow stronger, while others sought strength in taverns, fortifying their spirits. But peace could not last forever...
What disrupted this idyll? An invasion of monster girls who desired only one thing—to take pleasure from the kingdom's inhabitants. The wise king began fortifying defenses to protect his people. But will he succeed? It all depends on you.
About the Project
This is a tower-defense game, but with original additions: the enemies are not zombies, but lustful monster girls. The game also features an upgrade system for your valiant defenders, allowing you to better handle increasingly challenging waves of enemies.

I finished the game but I don't know when the new update will come.
The game is gone.
It's all gone
you can find and download them from google or just look at peoples collections to get those games
Thanks to "Collective Shout"
I think alternatives will appear soon itch.io for NSFW
2-8 act you cannot finish it. it never ends
Just restart the level
doesnt work, im using windows
does work, I've had a number of levels that wouldnt end, sometimes I had to beat them about 4 times.. games ends on Scene 3 - lvl 4 I think
So i think i found a Bug,
I am in act 3 but the gallery for act 2 didn't unlock.
Also, i'm Stuck on Stage 3-4 because who uses arrowkeys in 2025? :D That shit is older then me!
When the new version public gonna release?
how do i beat normal mode for 1-8, its like impossible
put the farmers in the second row and use bow in back and when you get the ground mine place that where ever the first enemy is
how do you even get farmers, lvl 2 is impossible becuase you dont get enough sun to put down the bow guys in time.
MErchant Upgrade
This is a bug in version 0.3.2. Complete levels 3-4, and the gallery will unlock
Hello, version 0.3.2 didn't update my current version (0.3.1). Any way I can fix this? (I'm on mobile)
It just made a new app
same here, which is a bit annoying because I'm not looking forward to grinding the game again
This is a bug. Fixed in 0.3.3
Thanks Dev :)
Very fun game. The stages actually get a bit challenging as you progress and you have to strategize, but once you have a good army build going it gets very easy at least as far as the free version I've played let's you get.
To anyone having trouble, prioritize the rich peasants upgrade and the wizard's ice wall, then spam ranged units on every level. My only piece of criticism or feed back would precisely be that the melee units aren't viable with how the game and the score system work. It's far better to lay down ice walls for defense and spam dwarves and archers to handle the monster girls.
There seems to be room for a few additional units, so I would suggest adding some kind of healer to make the shield bearers and ugly bastards more viable, otherwise they just get trampled as the game gets harder and more and more monsters show up, no matter how many defense upgrades you buy (maybe a seamstress since health is just the state of your clothes? That would be funny.)
Besides that what little story there is is suitably funny for the ridiculous premise with a bit of intrigue regarding the player character. The art is good, the game over animations are good. Not much more to say.
I'll be following the development of this game, hope all goes well.
This game feels like a parody of itself. Still better than what EA did with the original franchise
I've beaten chapter 2 but I don't have the gallery for chapter 2, is there a bug or is it not finished yet?
me too..
maybe I played easy difficulty?or demo version?
+well it work at when I complete stage 3-4
This is a bug in version 0.3.2. Complete levels 3-4, and the gallery will unlock
i'm a little confused, i've already beaten act two, however i can't see any of the animations in the gallery for said act
btw i'm on pc
This is a bug in version 0.3.2. Complete levels 3-4, and the gallery will unlock
free version seens to be broken at level 2 easy you start with 50 coins by the time you put 1 guy down there is already 2 girls coming down and when you finally put a second guy a 3 girl is already half way down the 3 lane and its impossible to make enough money to even put a guy down before she reaches the end and you lose
i will just guess the only way for you to pass level 1-2 is some kinda patreon code or something
You have to buy the rich peasants upgrade as soon as you can, later stages are impossible without it.
Very easy once you get that and a couple other skills like the ice wall for the wizards and the dwarven engineering buff.
ok no that was not the problem apparently is because i had an old save so because of that i only had the base boy and no shop making impossible but deleting the save and creating a new one worked
Can you improve the FPS performance when The Horde is coming is just decrease when many monster girls appears and fix the sell unit my game crash when I remove a unit
What kind of device do you have?
Infinix HOT 30 Play
Version 0.3.2 has already been optimized =). The next optimizations will not be available anytime soon.
Parkour levels are very unfriendly to mobile phone enthusiasts. When both the jump key and the move key are pressed simultaneously, only one key is always valid. Fortunately, you only need to use the jump key to pass the level
Do you have discord server?
I don't want to start over the game how can I continue the update?
I've already completed the game when I downloaded the update I found 2 copies of it on my Android I can't just start again it's boring
If you are playing on Android, saving progress when updating has been added in version 0.3.3
can you add chineae?
With the current budget, this is not feasible.
Can you add Chinese?
game crashes when picking up drop on 1-2, and you just have two guys you just can't use, which is especially frustrating when one of them is the sunflower so you're just reliant on coin drops. i can select them but not place them.

Delete the old save
does that fix both issues?
fixed, ty
game got stuck at the end of 1-6 at the final flag then when i tried to restart the game it spit out an error message and crashed.
Without a screenshot of the error, it's hard to find out why there was a crash.
Yo dev, it looks like the file you updated for V0.3.2 isn't that one, it's V0.3.1, pls kindly update it soon.
I checked, the version is correct. Why did you think it was version 0.3.1?
I thought that because i did update the game but it still remained at 0.3.1 and didn't update to the latest version
I can't seem to update my current version to the newest one on my phone. Is there a way to transfer a save?
Starting from version 0.3.3. game will not delete old saves.
Yo dev, Since V0.3.3 is out in patreon, will you soon release it here? If yes then will you release V0.3.2 publically?
Yeah, after the release Android V0.3.3
How do you beat the Vampiress (Stage 2 boss)? I can get her to the point where she transforms the first time but then i always goes to the loose cutscene, no matter what i do
Click on that circle repeatedly like your life depends on it
cool, thanks that did it, i just needed to reactivate my idle clicker gamer skills.
Can't wait for more updates! I absolutely love this game!
Waiting the .3.2 free release
Do we have a general idea on how long that will take?
¿Cuando estará disponible la galería para la derrota del jefe me gusta ver la escena pero no me gusta tener que perder y esperar que las chicas lleguen?
yes
It's highly innovative and truly entertaining — kudos to the developer for such a creative game."
On Android 15, when opening the page for the first time there are no issues. However, upon reopening it, display issues occur with the page’s width and size. The problem manifests as the game shrinking to the center of the screen, and it cannot be adjusted."
where is save file location in androind?
any help with stage 2-9? I cant seem to get past it
Has esto pon lo de siempre los que crean monedas,los arqueros,la mina,el barril explosivo,el hombre del escudo y por último el mago de hielo primero crea una linea de los de monedas,2 líneas de arqueros,una de hombres de escudo y luego conforme tengas más monedas sustituye solo 1 arquero por línea con un mago y guarda 150 monedas para la última oleada pon el barril explosivo y no debería haber problema a mi me funciona aunque si te digo la jefa es más difícil ahí solo te recomendaría que como no necesitas monedas guardes los barriles explosivos para su fase 2 porque vienen muchos enemigos y ella encanta a toda una linea.
Upgrade the Damage and Health of the Archer as much as you can , in the Shop with the diamonts you can from beating a Level. That way you can quickly build a defense line that is both low cost and effective.
Any help with stage 3-2 would be appreciated? I have issues controling the jumping and movement with andriod....I can not seem to make it through the the stage. BTW- the game is awesome!! I would definitely donate or purchase things if it was possible.
You have to upgrade your hero first. The value of level 3-2 is high.Of course, the most basic level can be passed. Place the mines in advance.Start by planting gold coins.The order of playing cards is fixed. Then fight with the basic hero.All the words are translated by machine, which may not be smooth.I can't read English, sorry.
when is v0.3.2 gonna be public cuz the v0.3.1 is too easy ngl
class3.3
希望能有中文翻译
希望将来能有中文翻译版。
Есть надежда,что в будущем появится перевод на китайский язык。
Hopefully there will be a Chinese translation in the future
really good game the plaforming level was a little hard, ngl cant wait to see the rest of the game also love the boss fight i just wish you can speed it up like everyother level
The new platforming level is unplayable. I have to wait a whole half a second just for input to come in. Fine for tower defense. Horrible when trying to jump over moving target. I don't have time mastering my future sight just to play porn game.
No es difícil si lo intentas varias veces solo hay que calcular bien y presionar el botón de salto 2 veces solo ponte un poco adelante así evitas las enemigas que saltan y solo tendrías que preocuparte por la que vienen corriendo y las que vuelan mientras no saltes cuando pasan superarás la fase sin problemas.
i did not download platforming game. this is tower defense. what does platforming doing in tower defense. it is like if you had to play a rhyme game to complete souls-like.
Entiendo tu punto yo también me moleste por ese cambio solo que no entendí muy bien tu anterior comentario ahora está todo más claro.
A mí también me molestó solo que no había entendido tu anterior comentario.
I'm waiting for this one in v0.3.2
I will skip the 0.3.1 because I have nothing to see in it.
I'm actually there for the gameplay to be honest.
We need mods on this website. There are too many spam links. Hopefully this problem won't bother you too much. Good luck 👍
