Greavitex...
Get it?? GREAvitex... GREAT??? ugh that was terrible, I'm sorry.
Anyway, this game is awesome, it is incredibly well done, and when I started playing the first level, I was like "woah, cool". I haven't had such fun with a flash game since Portal: the Flash Version, and that is a lot to say.
The music was also very cool indeed, thank god you didn't use paragonx9, because I think it's getting old.
Great game, 5/5, 10/10, and if this doesn't get frontpaged, then I don't know what should...
