One of the Greatest Games of its Generation
This action-platformer takes some of the best mechanics known to developers and adds in a level of story and character that has rarely been matched in the history of interactive media.
First of all is the story. Comical to no end and filled with instantly memorable characters, the desire to get to the next sequence and see the next piece of the scenery or hear the next quotable piece of dialogue.
Level design is altered from one mind (stage) to the next, while maintaining a constant rule set that keeps the player grounded in what they can and need to do.
Abilities are doled out at a regular pace allowing the player experiment and learn each, while keep an incentive to keep playing, as if the writing and variety weren't enough.
Just play this game, anyone who cares about classic games will be willing to discuss it.
