I love everything about this game.
Top notch idea, and execution. Art & music. Hard mode is super tight and a great challenge after you finish the game.
My only criticism, and it's something you probably know already and won't address, but it needs to be said:
It's a shame this is a coomer game. I love it, (I'm into shortstacks myself) but the general public will not like this. You could easily channel the meatboy fanbase, streamers + rage stream and general pixelshit lovers, but today your game is "problematic". I don't see any normie stream/review this.
The game itself is not even ecchi(except the costumes I see in your gifs), it's just the splash art and the complete game screen. My tip(I know, I know) is to follow nobeta and hat in time, and remove the coomer shit and leave it to fanart/mods. Keep it "cute and funny", if you know what I mean.
