It's fun, but that whole "off course" thing needs to be removed, because I see buffs there... so why aren't we allowed to get over there? That's dumb.
Also needs more, different upgrades. Perhaps some guns to shoot the flyers that slow us down, that's one idea.
Interesting, but hard to move around. I found myself accidentally evading every powerup and coin that was down there. And I never could use my mouse, sure I've got two arms but it's annoying to micromanage different things on different parts of the keyboard. There's a lot here to fix.
Crappy collision detection, thinks I'm hitting them when I am merely trying to get between them.
4/5 for the style, but voting 1/5 because it's broken.
Needs more space, easier management, etc. Couldn't get very far because I couldn't build enough of anything to make soldiers. And it could definitely use some graphics improvement.
