Flappy

Flappy is an action-puzzle game starring the titular mole-like creature who must navigate room after room of enemies and obstacles, only advancing once he figures out how to move that room's blue boulder onto the blue platform. It's more difficult than it sounds--each room has been designed to test your logic and problem-solving skills, and the puzzles become progressively more sophisticated. You'll also be menaced by Flappy's enemies--the simple-minded Unicorns and the aggressive crab-like Ebiras.
