Awesome classic!
When I tried the demo, and not being a fan of the classic C64 game, I fell in love with fantastic art, with that magical combination of sublime dream graphics and music. But at testing the design as far as game is concerned and quickly convince me that this was a masterpiece of the genre.
Perhaps some may complain that it is not a particularly easy game, but as a good heir to classical, Giana Sisters forces the user to give the best of themselves. With this, I can assure you that the experience of finishing a level is most rewarding, especially if we persist in doing it perfectly.
Awesome!
