Reall a very good game with unique graphics and great pacing. I like the power-ups, and the basis of history makes it all the more interesting. I think that the levels may last too long, however, I think the timer could be shorter to fix this. Also, hi-score tables don't appear to work.

out of 10...
gfx - 8.5 (really unique)
sfx - N/A (I have no soundcard)
design - 7 (timer too long, broken hi-score table)
gameplay - 8 (fun, fast paced)

overall, I think that this is a cool game with some neat features. I think the graphics could have fallen apart, but their application was very good. I am interested to see how you apply your style to other games!
