The Battery Vampire

Goal

Reach the green exit while unplugged — the vampire only hunts on battery power.

How you lose

The monster touches you while you are unplugged.

Controls & steps

1. Read your battery % and charging status at the top.
2. While plugged in, the vampire sleeps in the corner — you are safe but cannot exit.
3. Unplug your charger to wake it and unlock the escape.
4. Move with WASD or arrow keys toward the green EXIT.
5. Lower battery = faster monster. Reach the exit before it catches you.

Tips

• If Battery API is blocked, use the simulation slider at the bottom.
• The screen gets darker and redder the hungrier it gets.

Requirements
