Pretty decent for what it is, I think the wall jump idea you have is an interesting hook for the game. I appreciate the reset camera feature. The hitbox on the bones could be bigger imo but if you have a purposeful gameplay reasoning for the existing hitboxes I think its fine. Is this a downward spiral?

I played the demo, and I have to say, you really nailed the movement. I really like how Mel controls. I am not a fan of the CHOMP sound effect for collecting the bones, as I feel it's very abrasive. Also, if possible, please make Mel slow down or give some sort of better player feedback when Mel is clawing at he wall (signifying you can do a wall jump).  All in all, though, this is a very solid platformer. I would definitely play a full version of this.

-Collecting a bone will make the bone disappear, but its shadow won't until the collect sound stops playing.

-R1 to snap camera forwards has to be held for a second to fully transition, or else it stops midway. Not sure that's bad per se, but I reckon most people expect it to snap fully after pressing the button.

-Groundpound is way too fast, it looked like I teleported when I first saw it.

-I can't figure what 'drop' means. [later] oh for when holding onto an edge.

-Running on its own is alright. But, running and jumping into ledges feels odd. Also related to the air dash, it feels a bit snappy in an unpleasant way sometimes.

Got all  but one bone, the platforming in this level is reasonable for an uninitiated player. Keep up the good work.

Worked fine on Linux.

Controls: Same as "Beneath the Brine," I feel running should be a toggle here. I also find the double-bind of Shift for both air-dash and running weird. Why not put air-dash on space, too? Or on E. Don’t know about controller, maybe it all makes more sense there.

Level design: If you’re not going to add enemies, I think the levels should be, hm, more trick-focused? It feels silly/boring to just run in a circle to collect some bones in a random place, where there is no sense of danger or skill required. I mean, for a Level 0 this current one is fine!

Cheers

Idk what version of Godot you're using, but please use the AudioStreamRandomizer resource for things like item pickup sound effects. Just pitch shifting randomly on playback will make the sfx much less grating. You can also use it elsewhere for other really repetitive sound effects for the same benefit.

Controls nicely, but there is nothing overwhelmingly standout at this stage, I think one of the next things you need to do is give the game a more concrete identity outside of its platformer mechanics. Some game "juice" would be also pretty positive to work in at this stage, especially given the games more stylized nature. Stuff like pushing walls when you try to walk into them, ledge teetering, etc. Some simple particle effects (like dust while running, poofs in the air when air dashing, etc) would help contribute to good game feel, while being easy to swap out later.

It seem pretty good for me, but sound design will be the thing you will have to work the most for I thing. Animation is great. Tryed a fanart but I suck at furry so here this abomination.

Here are some more thoughts:

• should be able to air dash after a wall jump
• ledge grabs don't seem to work sometimes. worst case scenario seems to the the little pillar fountain at the beginning
• needs an animation for sprinting while swimming
• definitely needs particles for ground pounding at least
• don't know if this is wip, but a crouch action leading into a high jump seems like a missing piece
• remember to add a counter for the bones
• watch out for level design traps like asking the player to do a maneuver high up with no safety nets before making them do it on the ground more safely
