I was surprised to see the word "retarded" used in the game. It is a highly offensive and outdated term that I would recommend removing in the next update.
There needs to be a close range attack to knock people back, with the heavier guns equipped it is basically like signing a death warrant if you get swarmed
Way too easy and glichy prevents upgrades of strength and what not after a while. levels take too long to be interesting considering how that you can build all the dragons you need within a short time. Also starting mana upgrade makes rate of mana regen go slower
