The difficulty was just perfect to make me want to keep playing. My main feedback is because the moving platforms didn't reset when you died, sometimes your fire would go out before you had a chance to actually finish the puzzle before you got sent back to the checkpoint, and there wasn't much you can do about it except for hope the platforms were in the right spot the next time around. Really fun game though.
(also with all Unreal engine games, they launch in VR by default, so turning that setting off would make me happy, but obviously not your fault that it's still on)
