For those that have already enjoyed the original game, this is a fan's dream, with everything you could wish for and more, with nearly every aspect improved upon. A spellbinding videogame, and one that deserves to be spoken about in reverential terms for many years to come.
Edge has a lot to give you. You can pick it up and whizz through a few levels at your leisure and just enjoy the blocky, bleepy wonderfulness of it all. Or you can focus on becoming a master of the flashy balancing trickery, eking every last drop out of it, keeping your best times as low as they can possibly be, not missing one damn prism.
One of the best HD remakes you will find, with worthy additions to an already great game.
