I love ALL of the UI elements and appreciate the different sound pitch for landings. You've picked good way to introduce the story elements on-reports. The use of different colors in each area is great and I like the clean backgrounds.
It looks like the sprite could be bigger so traveling through the huge areas doesn't take too long but if the idea was to show the solitude in a wide space like this some more detailed backgrounds could make it look like an even more conscious decision.
The location of the first enemy right after getting the zappy skill feels like saying in level design language that it could be used on it - maybe to stun it? The range of the weapon is a bit unclear due to particle effect used for its attack visuals, seemed to ignore the wall when too close to it.
That's it for my nitpicks, overall good job and a really solid entry!
