I looked at it on mobile, so I couldn't actually play it, but can't you just fix a period and amplitude and alternate the phase forever or just set the amplitude to 0?
Yes, same frequency + smallest amplitude + phase adjustment is the optimal strategy
Arguably, minimal frequency + phase adjusted so the falling sinusoid has only negative values in the playing area is "more optimal" (more room for error).
Ha, clever. I guess the frequency should be limited so that the period can't be longer than the playing area.
Hello, I've added some buttons so you can look on it on mobile.
