good game, a bit too hard at start
Ya people bitch and moan about how hard the game is, but it's really only the first level that's hard... namely since you're bots suffer from the rain and lightning but the enemy does not. Once you unlock THEIR units, the rest of the game becomes much more fair.
however that is kinda bad design. The into/1st level should actually be the easiest level since it acts as an intro to the game. Make it too hard and you get people complaining about the difficulty.
Also on the twilight level i noticed things start to get buggy as explosions and bullets won't leave the screen... greated kinda funny when they all leave at once, but still, buggy.
