Nice game, you did some really good job !
Just for the next time, maybe find a way to avoid giving the player a way to finish your game faster than you expected, here I was always on my stilts and didn't shoot any pies so that I could find my way to the end quickly, I don't know if it was the way you intended me to play, but if throwing pies at clowns is supposed to be an important part of the game, maybe force a little more the player to do it ;)
The graphics are cool though, you used realy well the post-processing tools of Unity ! I also find it really original, the ambience is colorful and joyful, that's really nice ! It feels like you had fun making your game, which is the most important ! Congratulations
