Well, that was a really short experience.
I must say, despite the length of the game, it was fun to play! I very much liked the spaceship controls, which are similar to the ones used in asteroids. They're responsive, smooth, and easy to understand and use. I also like the levels, which are different in those from previously mentioned asteroids, and which are fun to play.
Although the soundtrack and sound effects are very good, the graphics could be a bit better. They aren't bad, and the leaping effects are nice, but perhaps they might be a bit too minimalistic. I'd recommend adding some kind of backgrounds, and maybe adding more colors over the whites and purples.
The main problem I had with this game though, is that it's way too short. Really, I finished this game in under 5 minutes! As I said, the levels are good, but still, there could be more of them.
To summarize, it is a good game, but the length of it is way too short.
