Not Taking Damage from Sayu onwards

[Mienshao]

Hi, is this a known glitch? During the Sayu boss fight, I was not taking any damage at all, and now I've reached the DK West fight and now I'm not taking damage, and neither is he.

Is something wrong? Did I put on some stickers that mess with the game or something?

[This is the greatest plan!]

The backstage pass sticker makes you immune to all damage but doesn’t save your score or awards you any fans. You can change your stickers either in zuke’s workshop in the sewer or in the pause menu.

The DK west fight is weird in how his health bar resets to full after you knock him down. I’d simply take his health bar as a suggestion and not pay much attention to it.

This is happening to me to. Is it really just a sticker that does that? Why would they add that? I thought it was some weird bug or perhaps I had put it on easy mode or something by mistake.

I've happened to use the Backstage sticker a couple times before, it's good for practice (hence the name "backstage") for hard-to-beat bosses without constant game overs. Tried to figure out how to parry all those notes for Yinu on Insane using it.
