Very nice little game you have here. Pretty fun and simple. The only thing I would say is that it took me a little while to figure out how the boost worked, and even when I did it was a little hard to control. Having the player be able to turn faster would help I think, especially when outside the planet. Also 90 seconds was a little bit long. I think 60 or even 30 would probably be better. But very fun and solid submission! I enjoyed it a lot.
