Space is Key
We don’t want to interfere with the way the makers want you to enjoy their game, but it might be wise to turn off the music. Space is Key could already make you go insane without it. After finishing it though, you will feel reborn! If you are able to finish it, that is.
Space is Key is not very hard to explain. All you have to do is use the space bar to jump your block over other blocks. Executing it successfully is a different story however. It’s a bit like explaining to someone how to cross the ocean; just swim! But do not despair, experienced gamers should be able to finish it in a couple of hundred tries. The game conveniently keeps score of that, and that’s not to drive you crazy, really!
