Ugh, I hope Kevin Flynn's lightcycle doesn't sound like a vacuum cleaner in the actual game, too (starting at the :57 mark). Anyways, looks pretty good, but you know me -- could be better!
Lacks polish. Most if it looks pretty GL Tron fan-made. I'm sure it'll be fun for a while though. Starting about the :35 mark, I LOVE that I can hear the classic arcade game (of lightcycles) in the velocity sound there.
