About Idle Primes
Idle Primes is a cursed incremental horror game about prime-number obsession, told through a PSX-style 3D world. You've always been obsessed with prime numbers. Now you're alone in your bedroom with a CD-ROM you shouldn't have found. Put it in the computer, boot it up, and start clicking primes. Use them as currency to buy powerful upgrades, automate discoveries, and develop increasingly strange methods for searching the grid. But the game on the screen isn't the only thing running. The deeper you go into the numbers, the more something on the other side starts paying attention to the room you're sitting in. Features: Search for prime numbers across dynamic number grids Unlock automation systems and powerful upgrades Discover new mechanics that change how primes are found Satisfying incremental progression with retro-futuristic vibes ████████████████████ Belphegor's ██████Read more
