Honestly? Not a huge fan of Zero Mission. It's definitely cool for what it is, but it really does hold your hand too much and the bosses are WAY too easy. And, yes, it's cool that the devs included so many intentional speedrunning shortcuts and skips for repeat playthroughs (where the heavy guidance is irrelevant because you already know where to go anyway), but that doesn't necessarily make a one-off casual playthrough more interesting. It kinda kills the atmosphere of the previous games, too, by leaning more into a heroic action-adventure vibe. Again, not bad by any means, but far from my favorite Metroid.
