The cuckoo clock seems to need to have a click happen basically just after the beat to trigger it seems, if I stay on the beat then two misses pop up each time. Though despite that, I just did a run and got 5 seconds faster than my previous best despite having very few clocks, not tapping a lot of the time, and getting to around 500 points max at any point, think just from hitting on the beat of the base clocks a lot. You did a real nice job of making a game that's a lot more interesting than it seems at first glance
