Loading up the game gives a bunch of gdscript errors in the console which unfortunately lock input, I was able to get to the right side of the first frame on my first playthrough but nothing would happen so I had to restart and was never able to move again D:
nevertheless I can see a lot of effort went into this and the movement was very smooth when it did work, I especially liked going up and down the stairs which worked flawlessly even when jumping on and off them. I also read this is your first jam, welcome to the family ahah! well done, keep going :)
