Games Like Primitive Shades

You and your friends decide to go urban exploring in an abandoned school that has become infamous in your area. But when everyone suddenly cancels except one friend, you head inside and wait for them alone.

To pass the time, you start messing with a strange puzzle you find in the school. Big mistake.

Before long, the quiet halls are crawling with bizarre creatures: blocky monsters, round monsters, triangular monsters… what are these things, and where did they come from?

Can you survive the chaos? Will you ever escape the school before the shapes catch you?
