Not sure if this has already been reported or not, but it seems a bit obscure, so I figured I'd post about it. I found an interesting bug with wall jumping, where if you tap the direction away from the wall and jump at the exact moment you start sliding (it feels like it's frame perfect), you'll jump straight up instead of away from the wall. It's a bit difficult, but in theory people could probably use this to sequence break certain areas of the game. For some reason, though, it only works on right-facing walls. If you try to do it on a left-facing wall, you'll still face the wrong direction with the jump, but it'll jump away from the wall like normal. Not sure how big of a deal this would be to you, and I imagine speedrunners would probably find some interesting uses for it if it were left in, but I figured I'd let you know either way. Here's a short clip I recorded of the bug:
Either way, I really enjoyed the demo! Really looking forward to the finished product.
