It's an autorunner where instead of moving your character to avoid the terrain, you take control (wink wink nudge nudge) of the level itself. You're a world traveler who came across a broken world, so you've taken on the duty of fixing it up! The controls go as such:
Left Click / Single Finger Tap: Drag. Drag blocks down to make a path for the traveler, and drag red magnets up to bring a block up to the path, pulling it up from the void below!
Right Click / Double Finger Tap: Dash. Dash through blue barriers!
