Space is key is a simple game with simple gameplay: you use spacebar to jump the different obstacles that are in your way. The thing is that jumping those obstacles is more complicated than it sounds. Each level brings a new way of testing your reflexes and the timing of your jumps but even if I failed horribly I found myself trying again and again.
Space is key uses minimalistic graphics. Nothing fancy here just colored blocks but it didn't bother me at all, this is one of those little games where gameplay is everything.
It was created by Chris Jeff, you can visit his website here. I hope you enjoy it, try to to make it to level 15!
