Thanks for commenting!
Spider: Maybe I shouldn't allow to be this close to the edge without turning in the first place? It looks silly anyway lol, I'll see what I'll do
Controls: Weird, I was sure the menus worked with the controller stick before but you're right, it doesn't now, but you can use the pad. I'll fix that.
Camera: That's definitely something I have to think about, the camera is good for platforming, not so for puzzling. Maybe I'll add a zoom button.
Rocks disapearing: Yeah it's kind of arbitrary for now, I'll add some visual to rocks that break.
Speech bubble confusion: I'll probably move the player character away when they talk to a NPC if they're too close
Lines in french: Whoops, I switched up a few lines in the locales.
Spiky walls are also a glitch, you're not supposed to be able to climb them, not sure what happened. Small rocks not pressing square buttons is intended as they're supposed to not be heavy enough. You can jump to drop a crate on top of another but yeah it's not ideal.
Thanks for the feedback, gotta squash those bugs
