The game really needs an upgrading system. It's dull right now, but when you have cool upgrades like nitro, rockets etc. it would be nicer to play. You should be able to earn experience points or gain coins in level and with that be able to buy upgrades and features! Show potential 2/5
But still too easy, I won with losing no lives -.- And it's not that my technique is so awesome, I just put those cloud-shooting-towers everywhere and I won :] Still not satisfied..
