beem is a puzzle game based around directing a beam of light through targets and around obstacles to power a mysterious machine called the light engine. reflect, filter, and split light with your toolbox of mirrors, prisms, and crystal shards.
inside the light engine, a beam of light follows the laws of optical physics. reflect light at arbitrary angles! refract light into its component colors - and bring them back together! use light energy to power mechanical components to get parts moving again.
a strange creature called the gremlin will be your guide (and best friend forever). he's a little crazy from wandering the subterranean for such a long time, but at least he is more amusing than tragic.
