This game is fun but there's a latency issue. When I match the tap directly on the metronome it never works, I have to sort of anticipate the metronome and be early and then i can consistently get it. I don't think this was intended, right? I'm on a macbook with a chromium-based browser.
In the main game the fast ones are lined up really well, but the slow ones are not synchronized to the beat it seems.
