Very polished game! I’m not sure if it’s intended or something about my system, but the slow response of the A & D key movement hurts the enjoyment of the game and makes it nearly unplayable.
Yes, it's intentional, it uses physics, and what it does is gradually add strength to it, the key is to give soft touches, because if you hold it down it gets out of control very fast, think like if you were blowing a paper, it would be something similar.
