About KeyMaster: Prologue Horror
Speedrun horror in an abandoned hospital. Use logic, find keys, and run !
You wake up in complete darkness. Alone.
No hints. Only your logic, the keys you find, and the impenetrable dark.
An abandoned 1980s hospital holds its grim secret. This is a speedrun horror: you need to think and act fast before the old nurse starts patrolling the halls.
You might beat it in 15 minutes. Or it might take you a full hour to find the way out. Not everything is as simple as it seems! You will face challenging puzzles, and your only protection is a manual save system. Use it wisely!
IMPORTANT: Be sure to read the in-game guide from the main menu! It's almost impossible to figure everything out without it.
Can you uncover its secrets and escape? How long will you last before you give up?
