Thanks for checking out my game!
I am still trying to get a grip on what makes good aesthetics in 2D games and will try to apply your suggestion to my next one!
Believe it or not, the character was originally the same size as a tile and forcing him to drop into a hole required a lot of trial and error. I already shrunk him by 10%, but it sounds like it needed more! Do you have any suggestions? Is there a general rule where the characters should be X% the tile size?
