Oh boy, okay. The original was one of the first adult Flash games I played (when I was definitely 18+), and for the time it was a fantastic game. The controls and gameplay were always a bit wonky, but for 2002 it was a top quality flash game and had a certain charm to it. Or at least I felt it did when I was eigh--teen. Eighteen.
This felt like someone started a sequel back in 2003, came back to it 16 years later, glanced over the design notes and concept art, and then opted to keep literally everything exactly as it was originally planned. It does not age well. The controls and design feel like what you would expect from a slightly skilled amateur, not a seasoned vet, and don't even get me started on the main man. It's like reading an anime parody. Gary Stu does not even begin to describe this man, he serves only as an extremely egregious example of a self-insert and living vicariously through ones' character.
My only explanation for anyone here voting this higher than a 3 in 2018 and beyond is that they're seeing it through the deepest hue of rose tinted glasses. The result of nostalgic sympathy, and nothing more.
