I saw that somebody in the request forums wanted this game hacked, since i'm just new to hacking, i thought i'd give it a try, and i think it worked.
Hacks are:
No enemies [UFOs, lasers, mines, rockets], distance allways 10 000, and the aim is 5 procent on every level.
I din't find any highscore button, btw, so please let me know if you found one., so i can try to remove it.
Hope you like ;D
