I just like the aesthetic of it all. Dunno if most of the textures and models are default unity ones or not, but the simplistic design does seem interesting for the subject matter. If you're not trying to go for anything TOO serious, I'd suggest keeping it or making something similar in terms of visual style. Something to keep it apart from the crowd.
Another thing - again I have no idea what you're going for with this game - it would be really neat to have the game focus on the platforming bit. The gif for the game basically sold me on it, crazy shit flying all over the place is pretty solid, and if you were to expand on that it'd be a pretty good idea, in my opinion. Just my two cents.
