Fun like tron... or Snake.
It's like the Tron lightcycle game, or snake. Two of my favourites. Both similar. One thing I noticed, and I think you should alter, is the trail should be an exact squar, and not rectangular.
If possible, add multiplayer. Great fun. I scored pretty low though,(1894) I didn't figure out what the warp did at first. and the ship destruction part is also pretty keen.
