Actually quite nice. It's smartly written so that the best way forward isn't just endless praise but engaging in conversation and returning compliments.
Sure, half of the game also involves simply selecting the option mentioning art, cats, or anime, but the game isn't long, and you have to learn these details first.
If you plan to add more dialogue, you could try to play with both aspects. I.e. keeping up an interesting back-and-forth instead of repeating the last word she said, also perhaps weighting in your latest responses (e.g. she thinks you're insincere if you compliment her 3 times within 5 conversations).
And with more dialogue, there's the choice if you want her to have the same hobbies and interests every run (so players can learn), or randomize them, so you need to learn and make associations during the conversation (but that would require a much kinder timer).
I don't know what the timer is based on, but it seems tied to the number of questions asked rather than your progress (or perhaps both?). Unfortunately, it means it keeps speeding up, so a couple of times, I was close to the end and made a mistake, and then it was so fast that I could barely even read the question, let alone the options or make a choice.
The “persist” option after she rejects you and leaves sounds a bit like being a stalker, though.
Additionally, in a pixel art game, it's important to ensure all pixels have the same size, and your world pixels are much larger than your text font pixels, for example.
Very well done for a game jam game, though. It's a reasonably scoped project that feels complete.
