A lot of CE2 is complicated to explain, but here are a few things to clarify:
228 Stars is a speedrun category in this game, and it requires that you collect every star in Adventure mode. There are separate difficulty levels, but the game requires you to complete every single level on Pro difficulty. This means finishing all courses in the least amount of time available in each level, and all Bosses with 20 (18, in one case) extra lives collected to have access to the final boss.
Hexagon, on Pro difficulty, is one of the most difficult courses ever faced in a 228 Star Run. Scoring 5 million points doesn't sound hard, but doing it in 6 minutes can be a run-killer. Note the difference in splits on 6-4 and my current time.
On my last WR run, I had to retry this level two times, due to deaths by ghosts (and because I died, I get less points overall). A near-perfect run of this course is required; this means a maximum of 1 death and quick judgment on frightened ghost patterns (after Powering Up). A twelve-minute time save resulted in a cut of about 16 minutes from my previous PB, and still stands today.
