This was really fun! I loved the puzzles. Balancing puzzle platformers can be difficult because you are trying to balance both skill and thinking. I found that I needed more time because if I missed a jump I would have to restart to test a combination of points. I think providing an extra 2-3 seconds on those difficult levels would provide the player a little more forgiveness in case they miss a jump. The only other thing I found was that the fire hitboxes seemed a bit big. They are probably accurate to the fire, but making them a bit smaller would lower the skill level necessary just a bit and give the player that tiny amount of forgiveness.
Other than those two things, this was an awesome entry! I had a lot of fun playing. Spreading out the points each level was a really good idea. The music matched the tone of the game really well and the puzzles definitely made me want to keep trying when I failed. This is a game I would definitely like to play more of if you decided to continue working on it beyond the jam. Awesome job!
