I found
this review for it. I thought it was nearly as stunning as the game. It's exactly how I would have put it. I'll quote the last part here:
As a free piece of software, the original Cave Story gets a perfect ten. This not-free, enhanced port gets a...
Score: 9.5 - Superb (9s are a hallmark of excellence. There may be flaws, but they are negligible and won't cause massive damage to what is a supreme title.)
The graphics still look a bit funny, but that's partly because it's such a big screen compared to my laptop, and partly because even though there's a higher resolution, there's the same number of frames to all of the animations. You'd think Nicalis could have added a few more to make it more fluid. The more detailed the graphics are, the more choppy it seems.
Also, I was personally disappointed with the new music. However, it lets you switch between the new graphics and old ones, as well as the new music and the old music. I think that the old music is as much of a work of art as the game itself. You have to load one of the .org files into Orgmaker to fully appreciate it. Just try following a few of the tracks. Then imagine trying to put it all together.
