Found a new way to soft-lock the game (or at least new to me):
At the very beginning of the game, after opening the shutters, while looking for the three girls to help setup the cameras, before you get the map:
1) go forward to the food court area
2) follow the left arrow to the room with the photo booth
3) follow the left arrow again to the room with the F1 barred door, and the B1/F2 stairs
And now you are stuck. No map yet, and no arrow to leave that screen, so you are stuck with three directions to go that aren't available yet (barred door, stuck gate, stair down into tree roots).
Is the developer on here? Is there a way to submit bug reports to them?
