Impressive :)
This is going to my favs, I commend your effort on this one, technicaly this is awesome, I've been playing with 3d projections and sorted rendering with flash and got some results similar to this, but nothing I could call a game. As a game it lacks a lot of depth though and feels more like a technical demo but it still deserves mad props! it's good to see some kickass programmers around :)
I won't say much more, I think you know your shortcomings, I just wanted to say that I thought this was a beautiful achievement, the graphics look great and the sound design is awesome.
Keep up the excellent and innovative work!
