Simple but fun. Enemies seemed to scale too fast until I decided to try thorns to keep up. Turns out thorns are broken as heck. By the 6th upgrade, I'd occasionally return more damage then I received. Endless mode was cool. Beat 100 levels before stopping and while my dice say they do 37 forest or 74 ocean (0 fire), my thorns does 700-3000 damage while I take only around 40. Broken but I'm loving it! Nice art/music too.
