Played the patched version through.
Great visual style
I would increase regen 20x when next to a barrel as it already doesn't go above half health
perhaps make every jump as powerful as the up-jump and raycast to ceiling to give an even more powerful one to snap to the top
glorping under the fan will softlock until death
sound when failing to glorp could maybe be something other than a 'good' sound, maybe Gary says 'I can't'
