The "sonar" mechanic is really interesting and you could do a lot with it. The bell's pitch seems random right now; maybe it could be used as a proximity thing where its pitch gets higher as you get closer to the key.
Sadly, I did not find the key even after a good while's search. I did find the eye though!
Excellent work!
Thanks for trying out my game! Yes, the bell's pitch is random right now and I also had similar ideas about changing the pitch of it when near an item / an item emitting sound when you get closer to it but I failed to add it in time. I'll probably add it to a later version, after the jam is over.
Great job finding one eye! It ain't so easy navigating when you're blind, eh? :)
