Cool game in general! But this cololdowns... It' s just impossible to deal with it.
The only thing that ctually works is a stone spell, because of this cooldowns. It tleast has quite a good damage, stops enemies and let's you get rid of many salamnders with one stone, by manuvering around them.
I'd recomend to make cooldown more bearable and it would be a very funny arena game. Maybe it would be good to improve damage of other spels too, because even when I'm using only one spell, I can't kill salamanders reliably with anything other than stone.
