Well, honestly it is a bit random. We've tried a rather difficult art style (converting 3D art to 2D) and the first attempt came out terribly. The second attempt is pretty much what you see right now. But we've never managed to properly finish it because the artist couldn't find enough time to work on the game the second half of the week.
Two things have come out poorly, color pallet (colors feel like they are washed out but at the same time they are tiring to look at) and the fact assets do not always match.
