Cartesian is a puzzle platformer developed by Betashark. You play as Sibro, a robot whose planetary mining expedition has gone horribly wrong. Explore the depths of an alien planet, maneuver your way through traps and puzzles using your reflecting laser, and find your missing crew members. Oh, and don't believe for a second that your team is alone in the darkness.
I've made all of the music available for listen+download in the Audio Portal, so stop over there and check it out.
