Hmm, I thought I definitely got it fixed in this version.
Will absolutely be looking more into this and thank you so much for your feedback, super happy you enjoyed it regardless!
I still didn't get any void echoes either, in firefox (v 148, which is latest version). Saw your description of them and defs didn't see anything like that. Completed everything else. Enjoyed the game, would have been nice to fully complete it though.
Some feedback - would be nice to be able to toggle off corruption leash, since corruption ends up being strictly positive, and also necessary for some of the later unlocks.
