Looks like the art is traced from, directly taken from, or directly imitating the art of pigmhall. It could perhaps be that this game is made BY pigmhall, but this itch account isn't linked on pigmhall's YouTube channel. Just thought I'd point this out.
Edit: Well what do you know, this person seems to BE pigmhall. Didn't know you made games! Though I shouldn't be surprised, considering your liking of electronics. Thanks for making this game! :)
Edit 2: Aww, super cute game. ^^
