As someone who plays through this game regularly, I did feel the difference. It didn’t take me long to get used to things though. I was jumping from platform to platform and dodging enemies with little to no issue. In terms of Samus’ general movement and overall game feel, this hack works fine.

The only part I couldn’t figure out was infinite bomb jumping. This is a technique that I have no issues with in the vanilla version of the game (and I don’t have issues bomb jumping in Super Metroid either), yet I couldn’t get it to work here no matter what I tried. I’m not sure if it’s a skill issue on my end, or if infinite bomb jumps are just not possible now. This is kind of a bummer for me, since I really like sequence breaking this game and infinite bomb jumping is a big part of that. A lack of bomb jumping isn't the end of the world or anything though. The game is still perfectly completable without it, and there are still certain sequence breaks you can do to break the game in half if you still want to.

Overall, this is a good hack for people who either didn't like the way Samus feels in the vanilla game, or for people like me who have played this game dozens of times and are looking for a different feeling experience.
