I agree with seriousGEO. The controls are fine on my end. A beautiful game all the way through.
I do have a concern on my second time through. I tried to create a new game, but when I got to the door it was open and I couldn't go through it. I thought it was a glitch, so I tried to collect the keys, but they're not where they were as if I got them. Can't continue on. I'll keep trying, I love this game and you should really consider a sequel.
