One of the most frustrating games I couldn't stop playing. The task of getting to 1000 seemed nearly impossible yet I never stopped playing. I've died in the 950-990 ranger a dozen times and now I just made 1014. Now I know what is meant by SPAAAAACE! Great game, could use a better upgrade path since the surplus of diamons at the end are useless. However, loved the simple concept, design, music, and gameplay. I give it a 4.5/5. Great job. I'm looking forward to Part II. Kudos!
