I did accidentally wall jump a few times, but I redid the jump normally (or redid the entire level) whenever I caught myself, so hopefully, that won't be a problem. I don't think I did but I'll accept a time penalty if I missed any WJs.

A new update this morning fixed the moving platforms, which along with not losing a ridiculous amount of time on the bouncy blocks, meant I actually finished faster than WITH wall jumps! I'll rerun that tomorrow to get a proper PB on that, not one borrowed from another category. Still confident that a sub-15 is possible; still not going to attempt it myself.
