That was a lot of fun! I like the mechanic of being able to use your health/flame to attack, while having to keep it burning. Making the jumps higher when you are smaller is also a brilliant choice. It looks like you had as much fun playing around with particle effects this jam, as I did in my game. Love the way your rain is stopped by the platforms, so the player can hide under them. Colour palette choice and parallax layers also look great!
Took me a few tries to figure out i had to attack the final pillar to proceed to next level. Just running into it reset the level. Completed the game and enjoyed it very much.
