great but
like Aderta said, may i change a little.. it is repetitive.. only diff in levels is it gets a litter harder and spawn more..
its impossible to get the expert score w/out spamming the next wave button.. i only used the basic tower, more of them, upgrade some in later levels.. after a while i only used the tower that cost a lot but does great dmg and speed, more of them, upgrade some etc etc..
its like, we would have finished this game if we had all the upgrades or you can never beat the game without upgrading..
but, this is the greatest miniTowerDefence that i played :D hehe
