Wow! This is wildly impressive, especially as a solo effort! It's very (very) rough around the edges, but it was really fun to beat. In spite of various collision issues, the electrokinetic mechanic is (mostly) intuitive and a blast to use! The art has a couple of awkward spots here and there, but it really captures the tone of the game mechanics, and contrasts well with the somewhat melancholy turns the story takes. It's just all around a good time!
I could not get the audio settings to work, but I might have just screwed that up. Either way, the default audio setting is quite loud, and the audio regularly peaked near or above +0.0 dB.
The turquoise font is quite hard to read (it's similar in color to the white outline). The bits of font that are in black or dark green are much easier to read.
For me, the camera jitters when following the player. This might be presumptuous, but I notice that it doesn't do that in the screenshots. I wonder if it's because it's lagging on my machine? (I.E. it might be a Deltatime-related issue).
Whenever I try to grab something in the background, I do have to make sure I'm grabbing at "where it intersects with my plane" rather than where the object is on my camera, which can be a bit unintuitive.
Also, I think the background's vertical position scales with the player's Y position, rather than the camera Y position, which creates a few confusing visual moments. 
Finally, as much as I love the game's art style and atmosphere, most of the animations are quite jittery, and the game has a lot of straight-up flashing lights, including the lightning on the title screen and the lightning on the G-Cell health bar. It's not the worst I've seen, but I would consider making them a bit slower.
All-in-all, fantastic! Great work!
