The controls are horrible. It took mashing the keyboard to find a way to actually start the game which turned out to be "k" for some reason. I tried to use the controls on the left side of the keyboard and found it painful to reach down to the lower level from wasd. Using k and l with it didn't feel comfortable either. On top of that according to the bar at the bottom this lasts FAR too long which even with a better control scheme wouldn't be enjoyable to reach the end with.
