WOW.
This game really is amazing, it reminds me of a game i have on my super nintendo, 'R-type'.
Was this game inspired by that?
Anyway, what i loved about this game, it had really nice grpahics, and clean programming, no bugs at all.
Congrats with this project, and can't wait to see more from you.
P.S you would do well at recreating Lylat Wars.
