OK this reminds me of the time you destroyed me in your split-screen dungeon game. This game feels like a plus version of that game, with more intricated mechanics and a better playing experience.
Pros: All of the battling mechanics are very well done! I know immediately what can my powers do, and learned with time how could I use them to counter the enemy. The art on characters are also pretty well done.
Cons: The UI and the ground sprite needs to be polished more. It's kinda weird to see a ground with shadows and a flat outlined character together. With a more coherent UI and more coherent art style, this game would be very enjoyable to play!
