We will definitely try and implement this in the future for all our games.
From the Discord: Bobo is working on it now. Basically the items are just borked in general as he's revamping the inventory, so hopefully it'll be fixed soon. Bobo will need to say what is best for this because I'm not sure without cracking the game itself open.

Bobo the Hobo is making great progress on this game, though he doesn’t have a set release date at this time. If you want to play the latest version check out his Patreon where he take’s community advice, and release newer demos of this game as he creates it. Bobo The Hobo’s Patreon
