Chirp is a small audio-forward prototype of a concept I had involving direct audio interaction with the game world. IRL things kinda impeded on my progress though, but I think this at least helps convey the feel of the core mechanic.

The primary way of interaction involves a microphone. Each door only opens to a specific sequence of tonal pitches and contours. Look for a hint somewhere in the environment!

This is currently very jank! I'd like to eventually revisit this and polish it up some more, as I really do like the concept. If others have trouble I can also upload a short video of gameplay.
