It was expected for your final level to get finished before mine :
This level is freaking clever as always. I really like how you modify the sprites for your own needs and use them in creative ways (after all it's true to the hack's name). Especially the disco shell plus muncher bit. You can use the bullet bill to feed the baby yoshi instead of feeding it with the dolphin at that one section.
I can relate to everything you said about exhaustion and removing some things as well
