Blue's Clues - Blue's Alphabet Book is one of those GBC games that makes learning letters feel like hanging out with a friend. You're basically helping Blue put together her alphabet book by solving little puzzles—matching letters, finding hidden objects, that kind of thing. It's got that cozy 90s Nick Jr. vibe, and the minigames are simple enough that even if you're just starting to recognize letters, it doesn't feel frustrating. My only gripe? The Game Boy's tiny screen makes some of the hidden items a pain to spot. Still, if you grew up with Blue, it's a weirdly nostalgic way to kill half an hour.
