I want to play through this whole game, because I love the art style, animations, characters, etc., but unfortunately I seem to have a skill issue, as I keep getting C and D ranks and can't progress past the first three levels.

Seriously though, I like how you've put a lot of thought into the protagonist's life and career. He's like a "loser protagonist," for lack of a better term, which is rare for Sonic-type characters. He starts out in a blue-collar job before getting fired and living in a junkyard. It's a really interesting concept and it feels relatable.
