Love the first track with the soul vibe and the "talking synth" - waaaay to long since I heard that last. The speed up at the end is also very nicely done and would really get the pulse going in a game. The rest of the music is also very good and would suit a high tempo game, and the ending of the last track really gives the feeling of it is all ending.
I imagined a different game than You described (listened to the music before I read what You wrote), but the basic premise would be the same.
Good work!
