I went left and down, which meant I didn't find the running shoes or keys to unlock chests. I eventually restarted since it was impossible to progress, and focused on the right, and managed to finish the game a few times.
It was just the first failed run that was extremely demoralisng, having to restart the entire game especially with the slow walking speed, not knowing when the running shoes will be unlocked or if my run will end up being stuck again haha
