As the ingame manual details, in case you missed, the game makes use of tokens which the player may show to a character to initiate certain actions. The player character should already have the necessary tokens in the inventory. Additionally characters have an invisible hunger meter that must be filled enough before vore scenes become available. And finally this is just a code experiment I made right before and during the pandemic as an engine test, don't expect much beyond the interactions available with Erik the Writer and Hector the Candid.
