Escape the Backrooms is one of multiple games to be created after the backrooms urban legend/creepy pasta hype. I bought it during a sale, to play it with friends on their stream.

The game itself starts in the infamous yellowish corridors of the backrooms, with each player spawning somewhere different in them. The first task therefore is to find each other, find a key that is hidden in the level and proceed. The game then takes you through various levels, all based on the backrooms mythos, like mostly empty office spaces, parking garages, tunnel systems, and more. Each of these levels feature some kind of puzzles, others feature deadly creatures like a dog with a human face that is louder than standing right next to an exploding nuke.
One thing we found out that seemed pretty counterintuitive is how coops map changes are done. To change from level to level, every single player has to be in the warp zone. However, the warp zones are not recognizable as ones and often led to us being confused on what to do, just to realize all we had to do was to assemble in one room, that didn't look like it would let us proceed in any way. Also, the game, in its current point of development, feels pretty buggy and rough. One of those dog creatures for example despawned on us, while being visible, there seems to be a lot of animations missing or cheaply done... You get the point, right?

The game feels a bit cash grabby, but it's also cheap. If you really want to try it out, play it with friends and buy it during a sale, but unless you're super hyper into the idea of buying the game anyway, I really can't recommend it.
