A Made in abyss parody game sounds pretty fun, and this does have the makings of something good. Definitely needs more player model assets and actions. A map would be super helpful too. A way to display a bigger background image would be nice, something like the text field being across the bottom instead.
Actually I just spent a bit of time and redesigned it myself. Pretty generic, but works. The text fields as they are are just to show you can have up to 8 options displayable, and you could remove the camp and loiter options since they are in the hotbar now. The hotbar being to the right of the landscape picture would probably be better, but these are suggestions in any case, so follow whatever you want.
