That's very interesting, I honestly never knew that. Thanks!

Not sure what caused this but I have apparently found a death glitch in one of the areas in Artaria. I took a video and posted it to twitter. This is the area you use the 2nd pseudowave early game to skip the emmi door cutscene. Here's the link: https://twitter.com/Joe__Almighty/status/1459015478039375874?t=_I_0qXphG8kYLOUrxGWUzA&s=19

Any thoughts on what may have caused this?
