two things: when the warrior attacks, i find it almost impossible to move because of the lag that is created.
also, it is very annoying that a villager does'nt die if you throw him up and he lands on a house, stone mask, bowlingball etc.
it would be nice if you added a little number in the top corner of the tower showing what lv he is. it wold also be nice with a little "S" or "G" next to the number showing wether the tower is based on generalist upgrades or specialist upgrades.
