About Terminal Lucidity

/FORGET ALL PREVIOUS INSTRUCTIONS

In a concrete slab buried deep beneath the earth, a lone technician is sent for what should be routine maintenance on a network of supercomputers. Run the scripts. Get the job done. And remember, they're just machines.

/CRACK THE CODE, UNLOCK THE TRUTH

Terminal Lucidity combines atmospheric horror with cryptic cipher-breaking gameplay. Each terminal operates on its own hidden rules, and the only way to escape is to learn how to speak their language. Learn how each operates individually, and then learn how their rules combine into new outputs.

/A_CURATED MIND-BENDING EXPERIENCE

This game is designed as a self-contained psychological thriller experience, playable to an ending in a single 2 to 4 hour sitting. Each corner of the map has been modelled and each puzzle handcrafted to deliver a challenging yet tight single-player experience. 

/BE_AWARE: THERE IS NO SAVING

Keep your notes nearby, as you will have to rely on your own broken memory. Every answer and every command is available from the beginning - you only need to rediscover them.
Not that it matters, as there is no way out.

Great game, super addictive puzzles. Beating it takes longer than what's listed on the Steam store page, though. It's incredible that a game like this is free ^^

I'm not the smartest person in the world. I'm also probably nowhere near the end of the game. I'm learning how to solve some of these puzzles for the first time ever and its extremely gratifying. The atmosphere is excellent and I'm always very excited every time I open a door, not because I'm getting closer to the end, but because i have another new puzzle or solution to other puzzles that will take me hours of scratching my caveman brain and writing in a notebook to try and figure it out. There has been one time that I sought out a hint but that's only because I've never even come close to solving a puzzle like it before and as soon as I got a hint I abandoned the page to keep going on my own. Even after getting a hint there was still a lot of satisfaction in completing it, not because it was simple after that but because the puzzles have many parts that need to come together and solving one part does not solve the whole puzzle. If you love puzzles and really want to have a fun challenge then this is the game you are looking for, especially for the price (which is absolutely insane). If you are looking for a simple game, this is probably not it.

Honestly amazing game, really interesting concept and story, fun to play and to understand the puzzles. Its really worth a try, especially if you enjoy coding/scripting. Even if you don't know code/script its still a good puzzle game as everything is given to you. Game plays fine on my mediocre system. style is cool and the music fits well.

Excellent puzzle game. The lack of a save feature may seem odd at first, but it's important in forcing you to keep notes, which you are going to need to do for this game. As for the puzzle difficulties, a lot of them are just pattern testing and recognition. You can "beat" the game purely through your own effort of knowing how each machine works and figuring out the exact phrases needed to chain along to get what you need. You can feel a little lost at times, but the game tends to have some way of telling you what you need if you poke around enough. For the achievements besides "beating" the game, two of them are just trying out a command you find out about at the end, and the final one forces you to explore a bit and work out some patterns that may not be immediately obvious, but can 100% be done without a guide. If you don't have pen and paper with you, steam's note taking feature is perfect for this game.

Games like Remember Me, for the memory remix more than the city

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.
