How to play
Get started
- Move with WASD or arrow keys through three dark caves.
- Tune sonar with 1, 2 or 3 to reveal different materials; Space sends a soft ping and Shift+Space sends a louder scan.
- Collect gems and find the orange exit while avoiding the creatures your sound can wake.
- Press Enter after clearing a cave or being caught to continue or retry. Escape pauses and M mutes.
