Before you start reading the rest of this review, I want to say that I played this game exclusively wtih friends, so my experience will be very different from someone playing solo. AND that I have only done the case file mode in this game, I have not completed the campaign, so this review will not be about the campaign part of the game.

Running around with friends, being chased by monsters in procedurally generated mazes, doing a variety of puzzles while trying to communicate with the limits of proximity chat, all of that combined is not that new, or unique of a concept, but labyrinthine does have enough variety to make and keep it fun.
There's a range of monsters which have varying mechanics and ways to counter them, theres a lot of different maps each with their own monsters, puzzles, and unique tiles, and plenty of customization which you unlock by a lot, and I mean A LOT of searching.

At it's best, this results in playing through a huge, pentagram stamped (you get one try, then the map dissapears from the mission board, and it has a special cosmetic) map with 3 friends, losing track of each other, all running seperate ways without any communication, all barely surviving, finding each other after 10 minutes of wandering around, finding the special cosmetic after more close calls with death, and all barely escaping the maze alive.
I still remember that game vividly, and it was one of the most thrilling experiences I've ever had in a game, I still use the purple horns we got from that game on my character because that game was so intense.
There's also been plenty of hilarious games. People activating sound sensitive enemies by saying "psst" and dying violently, making art on the ground with the glowsticks while waiting on someone else to finish a puzzle that they are clearly struggling with, and people getting jumpscared from the smallest things.

But the game also has it's downsides, theres a lot of times where you're just walking around, seperated from a friend, and not talking or really doing anything for quite a while, and then it just turns into a walking simulator.
Any map larger than small can be an absolute nightmare to navigate, let alone finding the cosmetic. Which is a whole thing of it's own, the cosmetics spawn in a random safe house inside the map, but the cosmetic itself is random too, and there has been too many times we've wandered around a maze for 15 minutes trying to find the safe house with the cosmetic, only for it to be something we all already have, but in light gray instead of white.
Some combinations of difficulty + map size can also be almost impossible. A tiny map with hard difficulty has so many monsters in such a small space that it's harder than a medium-sized extreme map.

This game can be such a mixed bag, but I can't deny the amount of fun I've had playing this game with friends, so my final score is sort of a middle ground between the worst and the best moments I've had in this game.

Final Score: 7/10
