found a bug, and some other stuff xD
when the shield is still active at the end of a level, the shield energy will be drained if you start the next one - and drained at double speed if you really activate it :D
one of the soundtracks during the game is used in a flash "compilatoin" of mine i made with a friend (zholat, also on ng)
watch "brainstorming" to find out where the soundtrack is XD (dont be too demanding)
the game itself was good, had nice graphics, but was too easy.
a solution would be deleting the health packs - or at least the 100% ones - or turning their spawnrate down to 1 per lvl or something.
OR to make the base weapons cost money - the railgun is just too good to be free.
