Conceptually- I like what's presented. We have a player that can only attack while stationary, and cards that represent spells and attacks. Something where you move through a deck of cards with each one being a different attack could be cool, but sadly there's not much presented here and an overall lack of polish.
I do think this is an interesting start! There is a fantastic idea here that can be explored with only a bit more depth of game play. More concise graphics and less bugs would clean up this prototype into something interesting for sure.
