This was fantastic.
Am surprised how well the... moonies (?) work. Especially with them grabbing onto you during the jump. If the ground group following you looked as majestic as it does in Pikmin then it would be the perfect mixture between the army of Pikmin following you and the cute mass of Pikmin on Oatchi.
Maybe have some of the moonies folow on a bigger delay so that it spreads out more? Though hard to give advice as I don't even know how I'd implement that.
However, as is they do sometimes stack up a bit too much by default, that includeswhen just standing around. You can kind of cram as many into a small minimal space so its hard to gauge how many you got somewhere, could be 1 or 50.
That out of the way, gotta mention again I love the moonies. They look super adorable, really good job on the animations there. Generally the designs are well done. The player character looks great and so far the UI is very cute. I really like that Tileset for the cavern with the moons and stars inside (though it looks like you gotta patch up some missing tiles or fix a few placements).
The weird walljump is not much of an issue as of right now, but I feel as it gets bigger it might become a problem.
To walljump you really wanna hug the wall as a player, and having to let go to walljump makes that wallhugging kinda hard.
Maybe you have an issue with the player input overriding the walljump. If that's the case you should be able to just skip the player input for something like 0.2 seconds. Not sure how well that would work, haven't implemented a walljump yet myself.
Also it's hard to distinguish whether moonies are fighting, sitting around, or following you, a little color change of the sprite or its outline could help.
I'm sounding way too nitpicky here, don't take that the wrong way.
I am really really really really loving the concept of the project, it made me super happy to see this pop up. And I already had a fantastic time playing through this early version.
Really excited to see where this is going
