I hated Epic Yarn
Ironically, taking the "suck" out of Kirby meant taking away a pretty major design element for him (I though everything else made the controls iffy; controlling "car" Kirby was messy). The music sounded like it wanted to lull you to sleep. The challenge wasn't really there. The game was extremely short (without doing quests, you could probably have it done in one sitting).
I *do* respect the challenge though. Even though you couldn't "die" per se, to actually get "Gold" ranks (or 'S' or whatever) was actually really challenging.
I dunno, otherwise, the game didn't appeal to me. I like the more faster paced Kirby games. The game looked brilliant and had a lot of creative ideas, but the gameplay just wasn't as exciting.
