The Ambition alone of this movie is outstanding!
Most of the levels work fine for me, but some levels there is just so much on there that mario can't even stay on the floor and just runs out of lives.
But most of the levels work just fine, and work really well. And the water pack helps for all the minor glitches, making a really well streamed game.
The Level designs are the best part of this though. It brings pushes the gameplay mechanics to its limits (and beyond it at times) which is not something you'd expect from a fan flash game. It seemed like a brilliant combination of Mario 64 and Yoshi's Island.
overall this was great. Any plans of Making a flash version of Mario Galaxy? It seems perfect, with the mouse and all.
