Really fun game. The sprites, music and sounds give it a nice old school vibe. And I like the parallax scrolling effect. Would be cool to get new spells as you progress.
Absolutely. I may continue working on this. I'd love to introduce a boss battle around level 10, or come up with some different arena types. I also have the idea of collecting power-ups as cards, and part of the game is managing which cards you equip for each round.
