Love the story, narrative, and the art!
It's almost perfect, but there is a tiny problem in UI/UX design, making it feel a little clunky and less polished, for example, sometimes the phone and the selection button overlap and blocking the choice button.
Can't go back to the SMS and email selection on the phone, but need to put the entire phone down, press the phone again to switch between those.
The repetitive dialogue should be able to fast-forward and be skippable, like most visual novels, so it feels less mouse-spammy.
However, I'm sure you will polish it up if you have enough time. Great work for the Jam submission!
