Once you get past about lvl 5 it starts speeding up, and you get more uprgrades.
I got to
2 Auto Turrents - Maxed range
2 Red laser turrents
1 Blue laser turrent
I either go to or around lvl 20 and was doing alright, then got OVERWELLED and annilated.
Still though, epicly great Defense game.
The idea isn't that bad but it is too hard.
The asteroids were invisible and i need to get mor cash for evury asteriod i destroy.
But it's like the BEST graphics i evur saw! :D
it's so dark to see the astriod coming, it should be brighter and more asteroid, the starting gun should have higher rate of fire but lower damage
