Just played your game! Keep in mind the rules of the jam - if you want to use VTM IP per Dark Pack, the only way to do that for a video game is either to obtain an official license through regular means, or finish the game in the duration of the jam. Just noting - you won't be able to continue working on the project, unless not using VTM IP, beyond the jam's limitations.
I've talked to both characters and nothing happened beyond that, the conversations looped and happened again - but the idea of a vampire bar bartender game is interesting!
