You should be able to quit the game without alt + f4.
I read all the messages but I didn't know what to do next, the game looks cool though.

The game seems pretty short I only got to the part where she thanks you I'm not sure if there is any more to the game.

mystery games are right up my alley! i think this fits quite well with the theme and i enjoyed looking through someone's past pictures and messages for the solution, it's a great idea, tells a story too. would appreciate some quality of life features like being able to move windows around in the computer. i had fun playing this game, good job!
