I really like the concept of this one! The artstyle is really pleasant and visually appealing to look at (also appreciated the neat lighting effects that you gave to some game objects)! I also love the intro, it was well done! The audio adds a lot to the feel of the game, but the music was kind of a weird fit considering the setting and the tone of the game. For the gameplay, I really love the concept and would love to see a sort of endless run or version of this game where the player has to climb as high as they can before falling! There are, however, a couple of issues with the game that could be addressed. I feel like the character themselves have the correct weight / gravity / fall speed to them, but the head itself feels too floaty. I feel like it would be better to not only add weight to the head to make it feel heavier, but allow the head to actually land and stay on top of platforms (usually found myself hoping that when I'm reborn I would land on top of the platform). Given the current weight of the head, players can just slowly inch their way to the top by quickly throwing the head and re-spawning with rapid succession and ignore the platforming parts. This is what I did to beat the game, because the game also doesn't have a restart button or pause menu, so if the platforms disappear they are gone forever and I would have to reload the browser to give it another go, which is brutal given how long the level is. Also, I think that the coins could also have some use (like power-ups in a shop like some people suggested).
Overall, I still had a lot of fun with the game! With a few control fixes, and also maybe consideration for remaking the game into an endless scroller (which is just a suggestion and my personal preference), this could be a really cool concept to explore! It was fun just flying my way up to the top! Hope you had fun with the jam also! Great work!
