Pretty interesting concept! :) But I think that there were too many controls to get (WASD, Shitft, Space, Enter) and I feel if there were less features (switches, for example, don't really seem very important), it would have been a bit better :). Also, I couldn't pass the first mission, it was just too hard, at least compared to the tutorials. While sure, I knew how to use what, but I didn't know when to use them. So I would have liked if the first mission was easier and the next ones (if there are any) would be a bit harder than the previous one.
