While I haven't played too many of the other modes in VVVVVV (a couple of the time trials and the guest-created games), it is definitely one of those games where the core experience doesn't have a whole lot to offer once you beat it. It's still a lot of fun to play through, but it won't provide the lasting challenge that Super Hexagon does. That's not a knock on VVVVVV... like Cavanagh said the other day, they're very different games. I've beaten VVVVVV a number of times on both the PC and 3DS. Great experiences with wonderful level design. Some of the best pacing, too. Love that I can sit down, play, and beat this in one sitting. In that sense, it really takes me back to the oldschool days.
