ASYLUM

 You wake up inside an abandoned asylum. The lights are out.

  The doors are locked. And you are not alone.

  Armed with only a flashlight and dwindling batteries, you must

  navigate a maze of decayed hallways — collecting keys to unlock

  the exit before the darkness swallows you whole. But the deeper

  you go, the more of THEM there are.

  ── SURVIVE THE DARK ──

  Your flashlight is your only tool. Use it wisely — every second

  it runs costs battery. Sprint and it drains faster. Let it die...

  and so do you.

  ── COLLECT. ESCAPE. REPEAT. ──

  Find all 3 keys hidden throughout the asylum to activate the exit

  portal. Then get out. Every level is a new maze — procedurally

  generated, never the same twice.

  ── THEY ARE HUNTING YOU ──

  The patients here don't sleep. They patrol the halls, respond to

  sound, and chase on sight. Lose them in the dark — or don't.

  Their glowing red eyes never stop searching.

  ── HOW LONG CAN YOU LAST? ──

  5 escalating levels. More enemies. Fewer resources. Bigger mazes.

  Your score is tracked — can you beat your own record?

  TIPS

  ─────────────────────────────

  • Don't sprint unless you have to — they can hear you

  • Enemies can see their own eyes in the dark... so can you

  • Medkits are rare. Use them wisely.

  • The exit portal glows orange — but only once you have all 3 keys

  • If they're chasing you, break line of sight and go dark
