Ink

INK is a minimalist platformer where the player controls a white square, and must get to the exit on each level. All walls and platforms are initially invisible, and must be gradually revealed by splashing them with colorful paint; a splash of paint erupts from the player character whenever it is killed or does a double jump.

In addition to double jumping, the player character can grip onto vertical walls, which is instrumental for navigating many of the levels. Dangers include stationary spikes, roving enemies (which must all be defeated by jumping on them in order to open the exit), and cannons which shoot homing bullets.
