No, those felt OK to me, and the challenge of the spring is essential to the game. I meant the control scheme, in that I had to stop and think about what buttons to press, and in what sequence, to get the outcome I wanted. Something more intuitive, maybe WASD and arrow keys simultaneously (instead of switching), would have let me focus on the game instead of the controls. Or maybe it would be better with a controller?
Did you try different control schemes, or was this just the one that made sense and you stuck with it?
