I manually clicked my mouse to spawn a ring every time the song had an interesting note or beat, so it's more fun to watch now. Also you can control the tunnel direction with your mouse (10-second latency), and there's more space stuff floating around. You can also adjust the audio latency in case you have bluetooth headphones or other slow audio devices, using the spacebar to show a slider. My JLab JBuds Lux, for example, have about 0.4 seconds of latency. Adjusting this will help the rings sync up better. If you're unsure how to adjust it, the project can do it using your input. To do this, hold down space and press the flag, then follow the instructions. It will play 32 pop sounds, and once you've clicked to the rhythm of them, the audio latency variable will adjust to whatever the perceived average latency was.
