Only one hour in and I am hooked! This game is the perfect balance between story and interactive detective game. Even though it's only the first chapter I've already had it make me laugh and the atmosphere is great at being creepy while being kinda cozy. I highly recommend this game it's worth checking out!

First of all, I cannot WAIT for the next chapter! The story and art is so good. It really had me hooked and aching for more when I reached the end. I played it on Steam Deck, and it worked fine after I rerouted the controls. I did have to restart once during the final stretch because I wasn't able to speak with Ray to present my findings, but I'm really not mad for it being in early access. I do wish that we could save at will versus at set points. Having to restart and go through all the dialogue and fetch questing in Josue's house wasnt too big of a pain, but still. And, personally, I would love the ability to have the MC shower at the end of the day because no way he's hopping straight into bed after all the gross mushroom horror, haha. All in all, I definitely recommend.

This is the second game i've bought and my first review on Steam. I'm really liking the game, the characters are fun, the whole narrative about being a worker in a Plague Control Department is pretty interesting and new for me(At least in my past games experience). I only encountered one bug that kept me from progressing the game but i managed to fix it by chance. The art is pretty cool, and the investigation fun (When i'm not stuck). Pretty excited for the next chapters.

Games like Remember Me, picked for the Memory Remix rather than the neon: minds you can break into, a vertical city to climb, and combos you build yourself.

Games like Noita, where the physics is the real enemy

Games like Noita for the two things it really does: spells you assemble yourself, and a simulated world that takes nobody's side. Seven picks, from a slugcat to a dwarf fortress.

Tormented Souls price: a horror game that stopped moving

The Tormented Souls price has not budged in six weeks of our readings. What that means for buying it, and whether the 2025 sequel is the better purchase instead.
