great game difficulty is a bit high, I am sure that what you were aiming for though, I had the same trouble as others where while moving normally speed is fine or almost slow but in a moving jumpits as if turbo engages and its hard to control your landings .
I suspect a controller makes this game easier.
some of your pillars or walls I got hung up on as well when stuck on a wall I can jump forever. Which really was the only way I could get my way through it.
