Nice new concept.
It's about time someone did something different with Snake! I like the 3D perspective here a lot. The polished floor effect you did, the sweet soundtrack, and the slick art combine to make a game that's actually attractive and worth playing for more than three seconds. The green apples are *great*, by the way... haven't seen that in other versions.
For future versions, I'd like to see some more innovation; maybe a changeable music option and extra bonuses or hurdles to get past. A life system and multiple levels with obstacles would be really cool... once the snake reaches 30 links, you go to a new level that's harder and/or faster and/or whatever. But, for now, this is a great step up from the typical Snake.
So, I bestow upon you the gift of a 5, which is something I swore I'd never do for a Snake clone. Congratulations.
(Uh oh. Glitch. I just ate 22 reds and 3 or 4 greens, and now no new reds are showing up. That might be a problem. You still get your score, but you might want to fix that.)
