Quick bug report: The wall jump mechanic is a bit hit or miss, on one room with 3 golden activated doors, I could not grip the right side of the golden block on the bottom of the page.
I couldn't reproduce the bug you ran into, so I'm not sure if it was a weird one-off (WebGL bug?), or just a weird and rare situation happened. Thanks for letting me know though, I'll keep an eye out for any other issues like that.
