Hey there! Just played through the demo and I'd like to report a small bug (I think) that I found on my playthrough. Judging by how inconsistent it feels, I'd imagine this is a bug. If you change your direction after a wall jump (whilst in the air), you can gain height as it gives you a small boost - very similar to neutral jumping from Celeste. This is cool tech if it's intentional, and if it's not, then it's a cool bug.
