Cool game. I like the levels, and the mechanics is interesting. I enjoyed playing the game, but I was a little sad that there only was so few levels, and they was easily completed. Hope to see more levels some day.
To increase the polishing of the game, maybe the fire hitbox could be a little more smooth (maybe use a circular collider), and some sfx and small animations would really pop the game to the top for me.
Continue the good work!
