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
