unit upgrades do next to nothing. waste of money and time.
It's weird how people say bunny spam is slow. Just upgrade your mana/food product, get a food mace - after that levels can be sterilized by a bunny horde in 2.5-3 minutes.
Words cannot describe how broken this game is in regards to archers. Somewhere in the mid-low twenties level-wise, I was able to assemble a wave-motion gun of archers that quickly turned everything into pulp. And I loved every moment of it.
this game is so fun
