Well, I wish they'd broken with tradition then. The game gets so much so right, but in a small number of things like this and the grapple beam, it drops the ball hard, which is all the more jarring given how great everything else about it is.
Anyway, on a brighter note, I scored my second EMMI parry which was as exhilarating as the first.
Well Metroid doesn't normally have a double jump in 2D, it has an infinite jump. Normally, you would get a High Jump first that just markedly increases your normal jump height. But here they did the double jump, and I do find it kinda odd.
The grapple beam swing thing I've never liked, hated it in Super and not much of a fan here. But at least here it gets other, much better uses. And once you get that Space Jump, you can ignore the grapple swing bits pretty much entirely.
