I like a lot about this idle game. I have one suggestion that could add some spice to it. Every sword you get is sword, every axe you get is axe. It would be nice if the type is changed based on rarity. For example; Basic=Short Sword, Magic=Long Sword, Rare=Broadsword, etc...
I just purchased the blizzard spell and it doesn't show up in the skill box on the bottom. I also don't see their life dropping every 1.4 seconds so the skill isn't working.
