I'm a big fan of the movement mechanic, it's fun to learn and satisfying to get right. The visuals and audio are excellent, and the planet explosion is awesome. It took me many attempts to get 3 stars on all levels. Sometimes I felt the punishment for bumping into an asteroid was a little too harsh - by the time I've recovered things have gone down the drain. The power ups were cool and added interesting variation. I wish they hung around a little longer as often they're gone by the time I slingshot back around. Everything has a high level of polish and juiciness. Really great work!
