It's a good framework, I might consider keeping an eye on this project, to see which way this project ends up going. 

There's not much at all going on at this moment, the gameplay is very basic. 

Have you considered  any  alternatives to just waiting for your mana to regenerate, opening your inventory to use potions all the time might get annoying in the long run when you even have them, and waiting around and watching a counter go up isn't much fun.

Definitely rough as you mentioned but also a great prototype start. Basics are there and with some work I could see it being something very fun. Just had one bug to report (since I  know I appreciate when people report them)...wind magic didn't seem to be pushing enemies for me. But good job and hope you keep at it! Would like to see what it could turn into!
