Time to work on the actual gameplay. Which is way more important but I needed time to think of things anyway, so I did the ‘boring’ part in the meantime.

The cube-planet rotates with 46 frames of rotation for a really nice old school cube look (like here http://youtu.be/LCAMdOlZVV0?t=5m38s), and the stars move parralax-ish for a nice feel of the planet rotating around you.
