Overall a really fun hack, some stars in the 3rd Overworld did take a bit longer than I expected to get, but nothing was unfair or a wild difficulty spike, a really well balanced game all around.

Notes:
When recording C15 Reds + 100s, I had the volume set a lot lower as I recorded another video for something else just before attempts, so the sound on that star is a lot quieter than the rest of the video.
I didn't include a game reset before C13 to make the Koopa run to the goal normally, but that is required for the Koopa to work.
I swapped versions from 1.74 to 1.74.1 part way through C13, as a star in that level was broken in the first release. This means that a few stars in the playthrough may be slightly altered in the version that you play.
