Tip for later levels: If you're close enough to the top of the screen, Missiles will explode without any bullets. Since they don't add to your score you can exploit this to help reduce the amount of bullets on the screen.
Hard badge is a tad easy for a hard. I imagine some of the bonus orbs will be a tad tricky, but this could have possibly gotten away with a medium/hard or two hards. Need sleep, but I imagine that this could well be my second impossible badge. Good game all the same!
Fort Defence in most games (100 odd less than the zombies) - Fort Safe!
Fort Defence in this run - over 100 of the horde - Fort Overrun. I better not lose from this..
Very good game up to the final boss. The problem with him is a couple of the attack types are impossible to dodge, so rather than a dodging game, it becomes a don't get hit x amount of times game. Shame really.
