“This game is hands down the BEST Backrooms experience of all time! The graphics are PHENOMINAL! The sound design is perfect! Overall this game immerses you into a terrifying environment that either makes you feel alone…”
“Pretty enjoyable. It's a bit slow at times. Opening doors takes several seconds, even if the door is locked and won't open. So I often felt a bit discouraged from exploring. And it is truly a walking sim. There's really…”
“Probably the most realistic Backrooms game you can find on Steam. I am obsessed with backrooms games and have played a lot and this one is one of my most faves now! It gives the perfect VHS tape found footage vibes,…”

“The Complex captures what it feels like to be in a liminal space, no monster, only atmosphere and tension. This is what liminal spaces were originally attended to be, uncanny and out of place. I heavily recommend this…”
“The first backrooms game that actually feels like an endless labyrinth of creepy yellow office rooms. A maze so big that it felt impossible to map out the rooms or keep track of where I had gone. I was quickly lost. And…”
“If you love liminal spaces then you will love this! if you play this game I beg you to play at night and in complete silence, the vibe of the game changes drastically. There is also so much to explore and find! as a…”

“Never seen something run as bad as this garbage on the stem deck oled. It is the purest form of "unreal slop" Edit: LOL I do not remember writing this, and I barely remember playing. I will update when I play again…”

“really amazing atmosphere . amazing graphics . the story well its a guy talking to a broken walkie talkie that just beeps and boops the whole time and saying oh this door is locked so... that to me is one of 2 flaws…”
“Genuinly THE best backrooms game. This is the definitive experience. It is scary in the best ways. THIS IS WORTH THE MONEY JUST BUY IT SO THEY MAKE ANOTHER ONE”
“Probably one of the most atmospheric horror games I've ever played. Very well made by such a little team of people who you can tell are passionate about their project. Finished it in one go, took me around 2 arounds to…”

“This game is fine as a backrooms title, that being said I don't think it's worth $20. Graphically the game is good, but lots of ghosting/other unreal engine lighting artifacts. The animations don't sync up with the…”
“Dude. I love the idea, but holy screen shake. I understand that found footage has that look, but this is a bit much. And, with no way of turning that off, this becomes unplayable. I didn't sign up for Nausea Simulator…”

“I've played a lot of backrooms games, but this is hands down the best version I've encountered and the closest thing to Kane Pixel's series. For anyone who only knows it as 'creepy office building full of enemies,' this is the perfect entry point into the lore. The voice acting…”
— a player, Steam review · 7 hrs played“This is a must play for anyone who is a fan of the backrooms. The environment design is incredible in almost every area of the game is terrifying in the best way possible. Overall this game is a fantastic improvement over its predecessor. The game seems to lack any audio…”
— a player, Steam review · 2 hrs played“This is the most immersive and polished backrooms game I've played. As there are no "threats" in the game, you're allowed to fully take in the atmosphere as you walk the endless halls of liminal space. As there is no immediate danger, the game will take advantage of that and…”
