I had this idea for a meme category called Any% No Boom Boom where you purposefully take a route where you don’t fight Boom Boom. Thoughts?

Do a run of it and then it could be on the extensions board.

Ok

I'd like to point out that the game makes the player fight at least one Boom Boom. You have to beat the large Boom Boom in World 5 to access the shortcut that skips Iggy and World 6, and if you don't fight him, you have to fight the flying Boom Boom in World 6 in order to progress through that world.

I think I see what you're going at with going through Iggy and World 6, but you're going to have to define it some other way because No Boom Booms is currently impossible.

We need extensions board now

It's not impossible because 6-T has a secret exit.

The flying Boom Boom is in 6-T2 not 6-T

No.
