Hello again Mofu-sensei. I hope you're doing well. I was curious about the gameover scenes, and I think that it was decided that there wouldn't be any cg scenes from losing a boss fight. And I also agree with this approach. But one thing I actually liked from your approach was the little funny image from losing to Remy in the beginning of the game. If we could expand the idea to various simple images that could show what is going to happen to Nene from her different boss fight losses, without actually showing the actual scene.
For example: if Nene lost to someone, that image could be of Nene being tied up on a large stick being carried away somewhere while begging(in a funny way). Or if she lost, it could be her trying to run away from the monster girl she lost to crying while being chased(in a cute but funny way). Or smaller/weaker girls out smarting Nene and trapping her, while that monster acts very smug mocking Nene etc. Something that doesn't make the gameover too serious.
Or other cases where she's completely restrained, lets say....by a spider girl who caught her in her webs and is about to rape her(that monster girl could be excited and is drooling out of her mouth). But again you wouldn't need to draw the actual scene, instead leave it to the player's imagination on what will happen.
This way the flow of combat isn't really ruined by encouraging players to lose on purpose. Instead loss will encourage you to play again. And maybe if you think it's a good idea, you could add a small hint about the boss fight. Although, I don't really think this part is needed since the fights weren't to hard. But let me know about this, and keep up the good work.
