This game is old after a couple minutes. Its just button mashing. I can play while watching TV. It started fun at the beginning of the series but now its just flashing lights.
Needs an option to skip animation to shoot faster and either fix the physics or give a bigger delay before comp shoots back. Blocks often seem like they fall in slomo.
Instead of locking a piece like kammat said Id rather see an option to lock a joint. If its part of the puzzle you could always have some joints unlockable. That would prevent the wiggling through long chains.
Game likes to stall, couple times have had two units in the same space, also some AI abilities seems to be without cd. Fix the few bugs and its a good game.
