This was a great game. So far I've made it to level 12, not sure how much more there is, or if it's infinite.

I almost stopped playing early because I assumed it was just infinitely fighting the same enemies. It might be nice to bring in some variety a little earlier to entice the player. Also, the fire spell felt so powerful that I forgot I had another. Maybe I need it more later on but so far I can clear almost everything with fire alone.

I think there may be a bug with the heal and the yellow potions. I was at 2/4 hearts and picked up a yellow potion. It gave me 4 yellow hearts but I still only have 2 red.
