It's a good game, The "out of control theme" is not visible at first, but with a few minutes it surely committed with the theme
The pixelart is constant in both,pixel scaling and color pallete, it looks simple and pretty, and the animations add a little silliness wich makes it more fun to play.
The sounds are good, but they could have been different to fit or create another feeling, and the simple music keeps a playfull  feeling, althrough it sounds a little bit void, it combines with the huge circus room, and when the wave is on, the theme fast pacing fits just right.
The gameplay, as i said before, fits with the theme the longer you play, if it wasn't for the mechanic of grabbing everything on the floor and use it as a weapon, it wouldn't acomplish to get that lack of control feeling
Circus mayhem its a great game for the jam, and i must say, when i open the game again to make the critique, it was hard to stop playing.
keep it up, i really enjoy your work!
