Love this!  Great UI stuff, story is always appreciated, and love that SFX and those graphics!  Great job on this!!!   There was some issues with screen scaling for the intro text crawl (some of the next was off screen), and not sure if I running into stuff actually did any damage or anything, but other than that it was awesome.  Also loved the meteor in the background of the first stage and like that all the stages looked very unique.

Nice!  The pixel art was great and the little touches like the working speedometer and chronometer were cool.
