Drift, spin, dash, and golf your way in a journey through interstellar glyph space.
Xenosphere is not terribly difficult, though not without challenge either. Note that the game doesn't have a save game feature as it's meant to be completed in a single 30-minute(ish) session.
An unlockable "high score" mode is also available if you want to test your skill.
Xenosphere also features highly adaptive algorithmic music using the integrated music software.
