Obviously it would be best if no one ever got stuck at all, but as a general failsafe and QOL addition, maybe something like being able to return to the last beacon you hit as a checkpoint would help.
You gave up too early after you got stuck. After your death you restart at the last beacon you hit just like you suggested! We've got a lot of changes upcoming including save codes like old school games in case you want to quit and play later and start at the last beacon you left off of.
