KRUNCH is a 2D action game with 8-bit style graphics where the player controls a Kron, a floating, mechanical orb who has to complete levels by navigating an environment, escaping aliens and avoiding obstacles such as spikes, gears, moving walls, bombs etc. Most of the obstacles kills instantly. The Kron has a limited amount of health and that drains at a constant rate, acting as a time limit. It has only one special ability, boost, which makes it go faster but also drains health when used. Health is also lost when touching enemies. During levels small orbs, Krebs, can be collected for points. There are six Krons and 100 levels divided over four zones with four boss chases.
