Very cool although a little slow
The graphics looks very much like the original. The blended scenes and animation is very similar and I think you've succeeded well on that. I'm curious how you edit levels. Is it all on the stage?
A suggestion for hit detection if you have no already done so - Only hit detect things that are near the player. You can break down the scene into parts and only have hit detection for the part the player is in. This will make the game a lot faster.
