This was really fun! Very intuitive controls and I enjoyed watching the planet rotate around in different directions as you fly over it. Having random planets keeps the game visually interesting. The short, fast-paced levels that can be played with one hand on the keyboard make this is excellent game for the casual gamer.
My highest score -- so far -- is 445.
Suggestions / Observations:
- On the "How to Play" toolbar, show the icons being talked about (Boost Pickup, etc), so the player can identify them better. The game is pretty fast-paced and there's a lot of "stuff" on screen so it can be a little hard determining if something is just a non-interactive background object or a critical foreground object.
- On one level, my player ship started inside the planet and took a few seconds before it "popped out" into the foreground where it was supposed to be.
I really think this game is worth expanding on!
