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.
