Again, this uses all of chapter 8's gameplay gimmicks in some really aggressive ways, like every room has tons of fireballs moving around that will get in your way and kill you unless you have impeccable timing.
I liked the beatblock section at the end, where it's in lowered gravity and falling forever, like at the end of the normal chapter 8. It's a lot harder than most beatblock sections, but still not bad once you get the hang of what to do.
Now there are C-side levels, and golden strawberries in every level as well.
Then I tried out Chapter 1 again, and it gives you a golden strawberry right at the beginning, but you can't absorb it until you get to the end of the level, and while you have the golden strawberry following you, there are no checkpoints, which means collecting the golden strawberry requires beating the level with 0 deaths. I could do this in Chapter 1 no problem, but the rest of the chapters I think I'll probably give up on that goal.
Chapter 1 C-side
Only 3 rooms long, but the last room is a huge gauntlet requiring some really precise momentum jumps. I beat it in around 100 deaths.
I still don't have the "Full Clear" time for this level though... so I guess Full Clear must mean beating the chapter with all collectibles in a single run.
