Frightmare

Frightmare is a horror-themed platform game in which death inside a nightmare means death in reality. Your goal is to survive until the alarm rings at 8:12, with each room visited advancing the clock by six minutes.

Explore a huge maze of interconnected rooms while facing zombies, bats, ghosts, and other creatures. Contact with an enemy costs one of your five lives. Guns can defeat some monsters, while crucifixes freeze enemies and clocks slow them down; your inventory can hold up to three items.

Alongside survival, you can raise your dream-state by killing monsters and collecting chalices, progressing from a “bad dream” toward more disturbing states. Getting lost is easy, and the game is designed as a formidable challenge.
