...What if the proof you existed started deleting you?

In Mado Marks, a short psychological horror visual novel, you follow a group of students who discover a door at the back of their classroom... A door that should not be there.

One day, they record vertical videos to their future selves...

The videos start as a joke. Half-cringe, half-sincere... Messages to the people they hope they might become.

Then they leave the room. It is the next morning.

The school says they were absent for an entire day. Their phones say only minutes passed. Attendance records are wrong.

And then one of them disappears...

Through subtle choices and shifting memories, decide how the remaining students respond...
