What a fantastic Game Boy game. I wish I had had the chance to play this when I was young. Excellent level design, great exploration with levels that change after the first time you complete them. Treasures never felt unfair to collect, and grinding coins was not a chore. The power-ups were fun to use, albeit limited in scope. Bosses could be frustrating, but nothing unfair. Definitely makes me excited to play the rest of the series.
