Definitely a rather ambitious project for game jam, and its great to see some experiments like this to test :)
I admit i wansnt completely surprised by the idea, since ive seen some videos of crazy people making games in apps like google sheets, but i was still very much intrigued, as you dont always see it done for a game jam.
The game features quite a lot of interesting and nicely drawn art, i especially love the cat :) However, sometimes it comes short due to the limitations of the “engine” and i feel like it does not work properly for me, because sometimes i felt a bit stuck because i could not click something, or i could actually move between slides by accident (eg. using the scroll button, but since some slides are duplicated with different data, i could accidentaly break the flow)
I still give you big props to you for trying this out though, it definitely was not easy. Thank you for the interesting experiment, and the little nice visual novel at that :)
A side note - looking at the pdf format, it kinda reminded me of a game book concept, but in a comic format :) Maybe you could try something like that in the future too, if you are interested in experimenting
