Each line is this game’s position on a Roblox discovery sort, sampled every ~30 min. A line breaks where the game dropped off that sort.

Each stem is one shipped update, as tall as the gap it closed — how long the previous build stayed current. The scale is logarithmic so one quiet month doesn’t flatten a year of daily shipping. Behind the stems is the same 10d player curve, so a build can be read against what it shipped into.
