nicely done. the controls are solid, it is visually pretty good, and the sounds are smooth. my favorite part of the game was that the speed power-up was a great double edged sword; it made it easier to dodge an enemy but sometimes sent you flying into another. I would have liked a visual or audio que that it had run out though, it got old trying to dodge and not realising that you no longer have the speed. other than that it was good.
