Very faithful remake, the new graphics and music are amazing. I also love being able to switch between the retro graphics and music just with the triggers on my controller, makes it super easy to see what certain things looked like originally.
Sadly, the gameplay is the same as the original, and feels pretty outdated. Some hitboxes feel awful, boss fights were just not very good, and the game would be helped a lot if it had a map, or some fast travel (the game world is small, but its juuust big enough where it feels very annoying to walk all the way back to some places after you die).
It's still overall a fun game, but you've gotta keep in mind that it is mostly just an old game with a new coat of paint.
