Really unique concept! I couldn't quite figure out the third level and then it started to glitch where the level restarted if I separated. Nice sound and music :)

Oh, that's pretty cool.
Conceptually it's similar to mine but execution is different, I lvoe the poppet feel of this. very cool! I think with some art work this could turn out quite pretty and lots of fun :) 

I really enjoy this type of games.

My suggestions would be - this game has no need for mouse controls. You could make this entirely keyboard controlled. i.e. - switching which part you're controlling with a tab on WASD control scheme. Separate with an E / F. So yeah, don't think mouse is necessary.

Otherwise, seemed pretty solid. Well done :D I had fun
