Sorry, kinda forgot to reply. I personaly think the art style depends on the game. For example graphics like thomas had enough would've just not fit this game and I don't want to limit myself due to the graphics. Pixel Art was one alternative I considered, but in my opinion it's just way too slow. And regarding post processing, I did have it, it just wasn't that strong. The bugs in the levels are mostly known, I just don't know why it happens.
