How does your submission match the theme?
There is only one action besides moving left and right. You earn points by jumping, ascend by jumping and even start the game by jumping! And you have to do it carefully since you destroy the blocks you touch, making you unable to stand on them. The game encourages you to jump by making you move slower on the ground, teaches all the mechanics at the first jump by putting a row of blocks above the spawn point.
