Looking at the graphics . . . they're rather nice.
But that's not La Mulana.
La Mulana is a triumphant an homage to the games of yesteryear, in terms of graphics, music, and above all gameplay and difficulty.
However, if part of that equation's changed, then it doesn't work nearly as well . . . Hopefully the port comes with the option to use the old graphics (and, if they update the music, the old music).
