What is this?

Found Horror Game 11.exe is an in-progress game about a collection of 11 different horror games that release after the community meets certain conditions in the Steam community tab. The game is developed and released by Yai Gameworks on and released on August 16th 2018. They're known for various other horror projects, most of which are made in RPG Maker.

The main goal, aside from finishing each game intentionally, is to locate 3 shapes. A Red Circle, a Blue Triangle, and a Yellow Square.
There is also a hidden fourth shape, a Green Diamond, found in each game as well.
Each shape is fairly difficult to find, and requires some clever thinking and sometimes arbitrary inspections of different places.

The list below will show the findings in each game
