GearBlocks is a game about creative building, interactive physics based machines, and gears - lots of gears.
GearBlocks pre-alpha demo - build 0.3.5796. This version does away with the fixed directional keys for part behaviours, and now allows you to assign keys to control motors, servos etc. It also adds a new feature where you can save out individual constructions and respawn them later, along with some example constructions to try out. There are also some other improvements to the motors, and a few bug fixes. To install, unpack .rar file into any folder. See Readme.txt for keyboard / mouse controls and release notes.
