Its good, though the space bar takes more time to rise up and also makes the most noise. Having multiple keys doing the same thing or just a way to rebind would be better

I guess I chose the space bar as it is a straightforward choice and easy to hit even when switching hands or fingers.
I'll consider adding a way to change keys though, as it is a valid point.
Travel time of the space bar can indeed affect the game a bit, though I don't think it's too much of an issue in this case as you're just racing the computer :D
