Its a cool game that is surprisingly calm although I think that you could make it so that the keys are disabled before you look at the sign that tells you how to do some of the things
Mean the idea was that you always could do it, just that you didn't know how to. It's kinda personal preference tho, some people seem to think it's a really neat idea, while other, like you, say that the abilities should be unlocked, and not just learned about.
