A bizarre indie horror mashup where a man stranded in a forest desperately searches for a toilet while being hunted by a creature.

The "2020" in your search likely refers to the surge of similar titles released around that time, such as:

Instead of just pressing a button, players use a mouse-cursor system to "control the apparatus" for maximum precision. Why Is It "Interesting"?

A more "serious" business sim where you clean facilities, upgrade your business, and deal with quirky customers to make money.

The game gained a cult following on platforms like the Steam Store primarily because of its sheer oddity and "meme-tier" humor. User reviews often treat it as a philosophical masterpiece or a "life-changing" experience, though usually with a heavy dose of irony.
