I noticed a few minor glitches like fish sprites changing when hungry or the music slider also changing the sound effect volume, but the game is surprisingly addictive. I think it's the sound of the bubbles popping and just how many are flowing out after a certain point. I'm not sure I even understood what was going on, but I was loving it. Also the collection UI seems to show behind the fish, but I almost find the bug endearing like it's an actual pet getting in the way because they didn't know any better.
