Nice aesthetics and fun gameplay loop (although it did get a bit repetitive after a few minutes). It took me a few seconds to realize that I had to fill up all 3 circles at the bottom in order to cast a spell, but once I did, it was fun to combine different elements and see what sorts of spells I could cast. Some of them felt REALLY overpowered, and I'm also not entirely sure what the purpose of mana is, since it seems to regenerate immediately after using it.
