SNKRX for me. Minute to minute gameplay is very simple – all you do is steer your train of dots left and right around a small arena, but the depth of strategy and the skill cap is surprising. I got many hours out of it. Also there is a mobile version!
Most of mine tend to follow this format:
filename: brief description More in-depth description and rationale if needed
It’s not often where I will modify multiple files within a single commit, but if I do, I will typically use a section or subsystem name rather than a single filename.
