This pay-what-you-want trifold horror duet game looks neat. It's really nice that the two characters involved don't have to be in a romantic relationship, the 'Devil' concepts are varied and don't require a religious horror angle (though you can opt for that if you want), the prompts feel well suited to the premise, and the mechanics of the tic-tac-toe board are a fun and innovative part - I especially like how this influences the possible endings.
It's a jam game, so was produced in a short space of time, and as such could do with some slight improvements - e.g. mentioning the fact they're going on a trip in the opening paragraph that gives the premise (both on this page and in the product itself), clarifying on this page that the relationship isn't assumed to always be romantic (makes it more accessible to players who prefer to avoid that dynamic), not having the example board be an image beneath text (this makes both harder to read), not having the 'you me devil' aesthetic text be an image beneath text (again, harder to read), more consistent line spacing in the 'Relationships' column's bullet points (it's got line breaks after each paragraph, unlike 'Locations' next to it), slightly tighter wording to save vertical space in that column (lots of wasted white space on various lines at present) - the example board could probably be slotted in below this if it's attempted.
In an ideal world, it would be nice to include a useable tic-tac-toe board on the sheet itself so that there's always one around if players lack pen and paper (e.g. if in a vehicle or at a convention). Tiny tokens could perhaps be ripped from the white space of the margins in a pinch - it might be helpful to have some pre-labeled ones in there for this purpose (e.g. "1", "2" and "D" for players 1 and 2 and the Devil) in spots where it definitely won't cut into any text on the flip side. For what it's worth, I reckon the physical damage to a printed copy could actually lend itself to the horror vibes and the theme of the damaged relationship. Bonus points if there are multiple sets of pre-printed tokens on the edges, so it can hold up to a few uses in this way.
Overall, looks like a promising game! I hope this feedback was useful. ^_^
