Hello, I'm stuck or rather I can't find how to get to the next part: there is a place that I should perhaps have access to (x:34 y:15) but I would need a third jump (and not the third jump on the side ^^)

Currently defeated Nazrin and Ichirin , got Double Jump and Water Breathing, Straight-, Tomahawk- and Boomerang Dokkosyo and the Lv.3 Sword. And seeming how unlike the Youmu game switching clothing doesn't seem to affect gameplay in any way, I have no idea how to proceed since unless I'm missing some way to triple-jump I have no clue how to deal with any of the remaining obstacles. Anyone know what to do next? I intentionally went for no-defeats because if the Youmu-game is any...

Thank you.

I've gone through just about the entire map and can't find the ground pound anywhere, effectively locking me out of the Power Room, Ice area and the Library. I've managed to get all the way to the final boss at the top of the map without it though. Where am I supposed to get it? Was it supposed to be after Shou instead of the air dash?...

Soooooo, how the hell am I supposed to beat this boss? I'm barely any time into the game, and I just get sent to the prison over and over. The crystal attack seems completely undodgable, and she uses it so frequently I can barely even dps the boss.
