The Legend of Zelda: Link's Awakening
This game was the first handheld Zelda game. It proved that it could be just as good as the other Zelda games on the bigger consoles. After the original, a remake was later released featuring the new mysterious colour dungeon, which basically focused all it's puzzles on colours. It was called Link's Awakening: DX (dungeon extra). Don't ask me why, but this is one of my favourite Zelda games.
