I have an idea for a 100% category where you collect 7 chickens and 4 orbs in one playthrough of the game as fast as possible (i believe there are only 7 chickens and 4 orbs) First run I did was a 5:53 with 8 deaths (3 intentional deaths)

well, calling it 100% is a bit wrong since there are more than 4 orbs in the game. But max% would be an idea?

max% probably. Get all collectibles obtainable in a single playthrough of the game.

so it would be 7 chickens and 4 orbs?

im pretty sure. there might be an 8th chicken in the castle but ive looked everywhere and can only find 1
