Kalm

Kalm is a side-scrolling platform game starring a man with a gun. This man can run, jump, double-jump, and fire his gun at anything that threatens him. His goal is to make his way through three maze-like stages, avoiding death. In each stage, there are multiple keys, which will remove barriers of the corresponding color. These barriers block the path forward, so they must be removed, but he must be careful as they can also release dangerous enemies.
