Wow, what a fun game concept! The animation in this is so reminiscent of Fancy Pants and those types of stick man games, which makes it feel really smooth, and it's so fun to smash into people/objects. I love how downright fun and silly this game is! How many more times can I say "fun"? Cos that's what it is!
Only minor feedback would be that the instruction "shake the mouse in a circle" confused me a little as I didn't realise I had to hold the mouse button while circling, I thought it was just tracking the movement in general, but I got there after a moment!
