they're all way too easy for me. still fun and charming to play through but i lost interest with the games as an adult. if i'm spending time with a sidescrolling platformer its got to have some teeth
Squeak Squad and Amazing Mirror were pretty lousy. Amazing Mirror is especially disappointing since the idea had so much potential, but the clusterfuck design make the game a chore. Squeak Squad is just uninspired. Both of these games were made by Capcom.
I also found Kirby's Dreamland 2 very disappointing. I was hoping for Kirby's Adventure on the Gameboy, but it just didn't play as awesome as Adventure.
