The first thing that stood out to me in this game was the seizure inducing background; thankfully I'm not prone to them. The idea behind the game play is a good one; although it took me a couple tries to figure out what you were meant to do. I'm not sure the execution was spot on. It seems like just touching the side of the falling squares kills you, which i'm not sure is intended or not. Also, there was a moment where I was way above the falling block and it counted as being crushed by it when I didn't even make contact with it.
The jumping mechanics felt a bit off, very fast and you fall about the same speed you jump.
Overall, it's a nice game, but I think it needed a few tweeks that would have made it a lot better.
