This is super cool, reminds me of something like that card game black stories.
I could'nt solve it though, I kinda got stuck after clicking on everything and trying to present everything as evidence, so maybe I got softlocked? Or I am just missing some out of the box thing.
I also wonder if you can actually do anything with the phone, or the shopping list. Can't seem to get either to progress, not sure if theres a way to do anything with that currently.
Overall, really cool game, hope to see an update on this! BTW: Your GDD is set to private, so noone can actually see that, in case you didn't notice
