I really enjoyed the art style and overall vibe of the game! Great little platformer. Only 2 things I really noticed:
1) I couldn't quite figure out how to actually fight against the serious clowns, my mouse input wasn't doing anything.
2) The space bar and mouse both jump the player, but I found that I could keep jumping if I clicked the mouse. Actually was fun flying through the level that way, but I'm sure its a bug haha
