This hack is quite good. There are no new tilesets, but the palettes are excellently remastered. Norfair looks like it should’ve looked all along, and many other areas are just stunning. No insane skills are required - you can get away with midair morph and wall-jumping - but some things are genuinely difficult to find; I missed the Screw Attack on my first run. It is often difficult to figure out where to go next, too. Not sure I’d agree with calling it open-ended, but the design is good overall. I’d heartily endorse this to anyone who enjoyed the original and wants a reworked version to play.
