…Iru!

…Iru! is a first person survival horror game in the vein of Clock Tower
and Echo Night in which you play as a young boy, trapped in a school with your
schoolmates at night. As your friends are getting killed one by one, your goal
is to escape this nightmare alive and to find out the truth behind those
deaths.

In …Iru! you must hide from monsters in chase sequences to avoid getting
killed. To progress in the game, you will need to talk to other people who are
trapped in the school, as well as solve puzzles with the various quest items
you can find scattered around the school.
