Crossplay

Is ...Iru! crossplay?

...Iru! is only released on one platform, so there is nothing to cross-play with.

...Iru! takes place in a high school with a large mechanical clock in the center. You control an upper classman who, along with his fellow students and teachers, finds himself locked inside the school when staying late to finish a project. As the bodies start to pile up your goal is to escape the school while saving your girlfriend and as many of your fellow classmates as you can.
