I tried using it while holding it and it said "you cannot use this alone" so I tried giving Tyler the pump and asking him to use it on me. He just didn't know
Ah, the fault would be of my own since that was vague enough to provide that idea. I should both update that fail response while also adding more NPC + Player interactions like that. I thank you for your feedback as I think I can make the game much more fun now :D
