Summary: I recommend this product to every platforming fan, from Mario to Rayman, this game delivers. It may be easy at first, but enough difficulty after the 3erd world or so and may things to discover, it is truly a keeper.
Summary: A little history lesson before I get to reviewing the game. In 1987, a glorious Mario clone came into the scene for Atari ST, MSX2, Amiga, and Commodore 64 systems. However, there was clearly a problem: Nintendo took legal actions against the company behind the game, due to how IDENTICAL it was to the original Super Mario Bros. As a result, the game was pulled off shelves within weeks after its release. So Giana Sisters never got to be a franchise....
Summary: I had actually heard about the original game on Wez and Larry's Top Ten Gaming Rip Offs and was intrigued by the very idea of the DS game when I happened to see it at a Walmart of all places while on break at work. Months later I decided to purchase it and I'm glad I did. Fluent animation, great music, decent difficulty level, tons of replay-ability make this as stated above a surprisingly good game.
Summary: Yes, Giana Sisters began life in the '80s as a game that was shunned as a "Mario clone", but we're now living in 2012, where there are a lot of different platformers out there. Giana Sisters structure is very much like Mario, but it's not a bad game at all. In fact, Giana Sisters DS is a spectacular platforming game with tight controls, lots to collect, and good level design. Graphics - Beautiful sprite work and backgrounds.
Summary: Giana Sisters is a must-play title especially if you are a fan of Mario Bros., as it basically pays tribute to the entire franchise. The difficulty starts off very easy but progressively gets more challenging in the later levels. The replay value comes from trying to collect all of the gems in each level. Doing so then unlocks a bonus level in each world. Highly recommended! Get this while you can because it was only previously available overseas.
