Has anyone here heard of this fan made hack of New Super Mario Bros. Wii - Newer Super Mario Bros. Wii?

I normally don't play hacks and fan made games, but I watched the trailer and it looked very interesting. So I went through the steps to download it and get it working on my Wii. After playing through it, I must say...it's better than any of the official Nintendo released games in the New Super Mario Bros. series. The level designs were more interesting, the worlds were bigger, there were more secret levels and worlds, more variety of just about everything. The game doesn't feel like a mere hack, but a true Mario sequel. It's not perfect...but in my opinion, this game blows all the official New Super Mario games out of the water. It's the best 2D Mario game I've played since Super Mario World. I don't know how long it will be before Nintendo shuts it down, but I highly recommend downloading it if you are a Mario fan.
