I loved this game as a kid, it was one of the first PS1 games I owned. As a kid I never could really get past the first World, but then a few years later when I was a little older, maybe around 10, I ended up getting past the first World and beating the game. I beat it a few times, and it was one of my favorite platformers, I enjoyed the World design, I liked the mechanics, and I thought Mr. Dark was one of the coolest villains. But looking back the game did have some glaring flaws, it was pretty hard and you had to be very precise at times or you'd die instantly, there were some cheaply designed levels and bosses that relied on trial and error, and the story itself is pretty generic. But like I said before, the game is a solid enough platformer with some decent level design and the bosses that aren't cheap are pretty fun. And if you can get over the difficulty, the game is good for at least a playthrough.
