There were multiple games I played that fiddled around with the idea of having controls be altered/taken away after certain things happen, and this game had a pretty interesting take on the idea. However, it's pretty easy as long as you can keep all of your controls, and once you start to lose them, there's no way to get them back, so it's a bit imbalanced. I think this game could work, but should have more balanced design: make it harder to keep your keys, but also implement some way to get them back. That way the game stays interesting.
