What a wonderful little game. Very relaxing and I've found myself playing it for far longer than expected. I've encountered a peculiar little glitch though. When I've played for long enough with the game on mute it becomes a bit slow to respond and the animations less smooth. If I unmute there's a loud blast of noise, as if many sounds being played at once, before going back to normal. Once that is done, it goes back to running smoothly even when re-muted.
