Echo Chamber
A puzzle platformer where sound is the only mechanic — players emit echolocation pulses to reveal hidden geometry in a dark world.
Overview
Echo Chamber is a 2D puzzle platformer built in 72 hours for Ludum Dare 54. The player character is blind — the only way to see the world is by emitting sound pulses that briefly illuminate geometry on contact.
Gameplay
- Emit echo pulses with [Space] — each pulse reveals platforms, enemies, and hazards for 1 second
- Limited pulse energy requires planning; refill at sound stations
- Later levels introduce resonating surfaces, timing puzzles, and enemy AI that also uses echolocation
Reception
- 4.6/5 Fun on Ludum Dare
- 400+ plays in the first week on itch.io
Post-Jam Plans
