UZA: The First Journey by DesertDog is an arcade action game similar to Robotron/Geometry Wars.

Quote:

Guide UZA through fifty rounds of frenetic action, where wave upon wave of relentless enemies test your speed, accuracy and coordination. Watch as your gameplay performance creates a piece of real-time abstract art. With only one life, how long can you survive, how much can you score, and what will your actions look like?
