This is quite the pickle for me. I intend on making a video showcasing all of this Jam's gaymes, and I can't record the material if I can't play the game.
When you said I at least have the source code, I got struck by this idea: I could totally make a 'recreation' of the story in the form of a 'video animation', and luckily this VN is a short and sweet one.
So that's what I did. While editing the video I made sure to match the intended portraits' expressions and done lots of dialogue copy-pasting. Only the assets within the game's files were used. (except the dialogue box, which I already used in my previous TH Game Jam showcase video, so it's really convenient)
This (unlisted) video I made should allow non-Linux users to at least experience the story and (maybe?) allow them to cast their ratings. And I get to make a showcase video that's not incomplete.
Please tell me if I got things wrong so I can correct them when I showcase this game in my future video.
EDIT: oops, comment is too long and the video is hidden behind the "View rest". Do you allow me to post a new comment with only this video (and short comment)
