Keyboard · Touch · Mouse
This game needs a keyboard. You can try it here, but touch controls are not available.
How to play
- Dig with arrows / WASD; Space or J sends a pulse.
- Face crawlers and pulse twice to stun, then clear them.
- Collect every crystal, clear every crawler, then enter the glowing exit.
All instructions
Use arrow keys, WASD or the onscreen direction buttons to dig through earth. Face a crawler and press Space, J or Pulse twice: the first pulse stuns it, the second clears it. Hold Pulse to repeat. Pulses travel three open tunnel squares and cannot pass through earth or rocks. Crawlers follow tunnels and slowly dig towards you. Collect every crystal and clear every crawler, then enter the glowing exit. Rocks wobble before dropping when the square beneath them is open: dig underneath, then step aside. Dark bedrock cannot be dug. Choose any of six caverns. P or Pause stops the game; switching away pauses automatically. R or Restart retries the current cavern.
