Just played it, it's alright. It's more slow platforming in the style of Yoshi's Island. Sadly it works in the same way as the NiGHTS DLC. It won't keep track of your score, no time attack and you need to get 100,000 points (which you can get just by playing a different stage) before it appears again after playing it. A couple of screens I took: Spoiler Can't complain too much though, considering that it's free.
