Art style is very nice, particularly liked the glowing edge and engine thrust effects. Well done for completing a 3D game in the timeframe.
Controls felt tight and responsive, making the ship feel satisfying to control. I liked the difficulty level and that life had to be preserved to take hits nearer the end.
The backstory of saving poor Brian was a nice humorous touch too.
For improvements, the volume level could do with being boosted. Also, perhaps add some epic music for an epic quest?
Overall, cool submission. Great job!
