This page documents information about Umihara Kawase. Many of the tricks demonstrated here are near impossible in real time and documented for the purposes of creating Tool-assisted Speedruns.
Weighted platfrom pulling
If you hook onto a platform from below, then grab the ledge in the climbing state, you will be both pulling the platform up will pushing it down. For whatever reason the game prioritizes pulling up in this case so the platform will rise instead of fall.
Up+Down ladder bug
Pressing Up+Down when near the base of a ladder and you will start climbing down through the floor.
Fast angled climb
When climbing a ledge that leads to an angled surface, after about a quarter of the way up if you press down to climb off, you will instantly be placed on top of whatever you were climbing.
