If you know about bisect and don't find it useful, my first guess is you aren't making enough commits (or you're squashing too many of them). Keep your git history granular, make intermediary commits when possible (as long as the intermediary step doesn't make it completely broken), and you'll be using bisect for a good chunk of regressions.

I love it. I even made a VR mod for it, and I find it even more fun in VR: https://youtu.be/zC-k2HTqg1A
