If it wasn't for the other comments, I wouldn't have realised there was lewd in this game ahah; I feel like the stages are too long and too easy, but mainly if you made the overall gameplay a bit more fast paced, it'd be more interesting - and actually risky, when it comes to seeing lewd.
Alternatively, you could have collectibles or something similar to unlock the lewd scene - as opposed to when you lose.
That being said, the art is very good, and the sound design is pretty fine for a jam game!
