Flatland

Flatland is a one-tap platformer game created by Martin Magni, which can be found in the Quest. It has 10 levels.

Gameplay
In this game, you have to tap to make the character jump. The character automatically runs and turns when it hits the left side of the level or the wall. Moreover, the character hits a wall, it clings or slides down to it. The character can also jump while in the wall. Spikes will reset the character's position to the start, but the keys are kept. Gates are unlocked if you have enough keys. To win, exit to the right side of the level.
