I don't want to be mean to the devs of this patch, or people who actively choose to play it. But as a fan of the original, I dislike nearly all of the changes this hack makes aside from putting doors on the map screen (seriously, I want a patch that does only that).
The original game was tightly designed for those original controls and the unchanged mechanics, and it doesn't need QoL. If you haven't played Super yet, please play the original first.
For some highlights emblematic of what I didn't like:
1. The GBA style controls are actually worse for two reasons: platforming is designed around walk/run, and Samus's arsenal is much larger than in Zero Mission. Having to press L+Down to aim diagonally down sucks more because you aim that way much more in Super's large rooms than you do in Zero Mission. You can't switch missile types/grapple/scan while morphed, which sucks in boss fights when you're evading an attack but need to switch between attack types at the same time (such as in the Draygon fight if you don't use the grapple trick).
And defaulting to run isn't a good idea because you're meant to walk before short jumps to gain tighter control. Jumping full throttle all the time is annoying for small rooms, boss fights, and when trying to use exploits.
Simply, Zero Mission's maps and fights are explicitly designed for these controls so those annoyances don't come up, but they feel clunky in Super which demands the increased control of the original buttons.
2. Distance needed to shinespark without glitches is way lower, to where it's incredibly easy to skip rooms with obstacles like the way to the Wrecked Ship. SM's design is balanced so that you can't break it on your first playthrough without prior knowledge, so that beginners don't get stuck or get to areas before they're supposed to.
This is incredibly important because Super Metroid locks the door behind you only when it's trying to teach you something. (and as a sidenote, if you play Super for the first time I promise you you're not going to get softlocked. Don't reload, you're not stuck).
Example 2 is a microcosm of why I don't like all the other "rebalancing" changes from Redux.
Lastly, the extra GBA heavy physics patch is just an insult to the original. This is the most fanboyish thing I'll say here. Super's floaty controls aren't imprecise and you will get used to them. And personally, they're more immersive in the world of Zebes (which I believe is supposed to make the game feel more alien, despite it being changed in Zero Mission to fit Fusion's engine and the GBA screen). The maps are bigger, so it actively undermines the experience. Anyways, I didn't play with it on, but I mention it because it looks tantalizing to new players who haven't gotten used to the classic control style.
Notes on this playthrough: I played up until Draygon on hard mode. I only didn't finish Draygon because I rushed through and only had 3 e-tanks. I like the inclusion of a hard mode especially since it's optional, it adds a new way to play where you can't rely on tanking hits as much.
