This game is amazing, maybe more upgrades, cars, levels etc..
Maybe some other tweaks, control of the gun, higher amounts of boost, maybe even a sandbox mode, bigger zombies?
overall great game, hopefully a sequel will be made
Every single game i was trying to make a new strategy, and every game, that strategy was completely messed up, because of those UFO's , almost every comment is about the UFO's and how much they hate them, please, as a update, cut down on the numbers, or remove them completely, im sure either will be welcomed as a relief and make the game more enjoyable.
