I pressed every fucking key on my keyboard trying to find the jump button before I found out that it was the spacebar. Admittedly, not my finest moment. The visuals are as simple as they can be and there's no sound, so the controls really needed to carry the experience. Unfortunately, they were slightly unresponsive, and the character gets kind of shaky when you jump which makes it a little harder to platform. I had that problem too while making my entry; I found that slowing down the speed of the movement and lessening the acceleration/deceleration of the gravity made things move a bit smoother. With so few pixels, there's only so much you can do to control the speed of things on screen.
