A mario esque platformer with a neat twist, you can hot swap between the two sisters, the music and environmental change. Each of them have their own abilities that can be used to solve environmental puzzles. It’s included with a X-Box live subscription as a part of the Games with Gold program. I enjoyed my time with it, though after about a dozen levels I felt like it had overstayed it’s welcome.
Holy crap! I remember playing ‘Great Giana Sisters’ on my dad’s commodore 64. it was pretty much a super mario bros rip-off, but was fun to play.
