You are Progress Man,
You start with nothing, and seek to become great.
Death cannot stop you, and every step forward is progress towards your ultimate goal.

Warning: The version this stage was made in, cannot handle holding 8 keys simultaneously. Be sure to spend your keys early in the shop, or do not unlock the weapon energy refill checkpoint door, in order to avoid a forced hard reset/softlock. Also checkpoints do not deactivate when a new checkpoint is activated in this version of the game, so be sure to time your checkpoint resets appropriately, or be aware that you can lose progress.
