Clear infected computer circuity of the viruses with your Salamanda Mk-1

Clear infected computer circuity of the viruses with your Salamanda Mk-1, the most sophisticated defense we have available.
Fight through enemy waves and destroy each of the bosses. 9 levels of sidescrolling shooter fun.
Heavily inspired by the classics - like R-type and Saint Dragon. This was great fun to make, though I think it's missing some extra fun aspect. Please let me know what you think I could improve in this game. I designed the games graphics, made the music in GarageBand and wrote the code, weee!
Cheers!
