Hey! Thanks for the feedback!
If you press ESC, you can choose to die or restart the level to prevent softlocks or reset a puzzle. The boot will always update to the next location you die to an arrow, so if it's stuck in a weird spot, simply die again! However, if anything becomes unfixable, you can press restart to do a full reset on your current level. Hope this helps! Also, you could fix this by pushing the arrow dispenser and getting crushed by the block. This actually should help with the puzzle too.
