sacrificing limbs makes the oxygen go into them at random (if you don’t hit the beat perfectly), and the oxygen requirements for the next dance move increases for the remaining limbs. but i agree, it’s probably easier to focus on one of them :D
yeah i also wanted to make it possible configure audio delay (or create an auto-config option). it seems that delay varies a little, depending on device and browser. we noticed such issues in firefox but it seemed to be resolved upon reloading the page (so that the game is cached). if it helps, you might want to try it in a chromium-based browser.
thanks for playing!
