Hey evapilot03, thanks for playing and dropping the feedback! I'm really glad you liked the core concept.
Good catch on the crash – there seems to be a memory/audio leak in the browser build when resetting the level multiple times. I'm noting this down and will fix the reset-logic for the next patch!
Quick question since you survived a few attempts: Did the 3D-audio tracking (left/right breathing) feel accurate to you before it froze?
Thanks again for testing!
