I was playing AISSON when on a dead run I accidentally warped from room one on 8-4 to turnaround room. I don't even know how it happened but luckily I was recording and I had an input display. I checked the TAS and the top runs, and they all seem to warp to wall jump room. Is this something undiscovered or is it already known?

I've been getting into the minus world ending speedrun and I've been wondering if there's a practice rom similar to the one pellsson made and if there is, can someone please link it to me. Thanks!!
