Simply put, this game is amazing for the GBA. It brings us back to when games we're simple and you didn't have to think that much to succeed. With the help of four buttons you can win. The presentation goes well with the theme, with well-designed characters and bosses and sprawling environment. The sound in this title is also top-notch, as the music never gets dull, even without voice-overs (which is understandable on the GBA). The only thing that bring the experience down is that once you've beaten the game, you have to repeat all of the levels and do a lot of back-tracking, why couldn't they have given us a few more levels? In the end, you'll be getting what you payed for, a solid action/adventure game for the GBA . The best part is this game is probably discounted now, so go pick it up if you're looking for something fun for your GBA.
