You pass by the doors on your left and right, and as you walk, the hallway seems darker and darker. Nearing the end of the passageway, you feel something below you snap! The floorboard gives out, and with it, you fall down an incredibly deep hole to a basement floor, breaking your left leg in the process.

If only you'd been able to see the decrepit state of the floor!

There is a small shaft of light far to your right at the top of an unseen wall, and a small hole in the wall next to you on your left. Your fall seems to have awoken something large and unfriendly in here, so there's probably only time to investigate one. Do you:

examine the small hole,
drag yourself to the shaft of light,
or stay here and try not to make a sound?
