I managed to do a dash-wall jump (my name for the tech used at the end of summit b-side) on a wall with spikes on it. I don't know how but I didn't die and shot off in the direction the spikes were facing.

Version was 1.2.1.11 as far as I know.

Is this known?

Yeah it's pretty well known. The only moment I've seen it used is in the recent TAS of Celeste () In reflection at the very start and that skips having to get Kevin to get up there.

Thanks! :)
