Really nice entry, I loved how you can combine runes and create new spells with it. Movement+sound was especially nice and art was on spot.
I didn’t like that turning around progresses a turn, as it led to a strafe moving. AI was also just dancing with me, while I wait for cooldowns to finish, as it wasn’t trying to take a shortest path to the hero. Game was incompletable for me, as at some level (lvl 5?) rune altar spawned in such a place that it blocked me from moving to other side of the dungeon.
But overall I really liked your game!
