Nice game! It reminded me of some older games with the graphic style and game mechanic of the fire ring keeping you within a small area to fight off enemies. I liked it! Is the "not knowing how the magic will behave" referring to the size of the projectile changing? I thought that was neat - implementing the theme by making the ease of landing a shot on an enemy unstable was a pretty innovative and creative idea! I think the only issue I had was that it was easy to accidentally not be in the battle fire ring. In my first playthrough I just ended up running into the boundary on the outside of the fire ring, then I explored the town, found the path again, and made it into the last fire ring arena. I also found that an issue - I didn't quite know what the right path was. Perhaps you could have something to guide the player down the path - like maybe signs along the road that point you in the right direction. Moving passed those two things though, I thought the game was good. Well done!
