I died on the moving platforms and had to redo the entire tutorial and story section. Not being able to stand on the platforms is a little bit of a problem.
Part of what made SUPERHOT so good was that you could take your time, and precise mouse movements weren't necessary to play the game. In this game, you have to constantly be moving, which means trying to pick up a gun midair is almost impossible.
Also, I can't pick up any guns even if they're on the ground...
I gave up after the first enemy encounter.
This game has a cool concept, but it was too difficult and the penalty for death was too much for me to want to continue.
