I found this more enjoyable than Super Metroid, mostly just due to the much smoother controls. However one of my main grievances from SM still remains the same; you get way too many missile packs. This makes the exploration quite unsatisfying compared to a lot of modern metroidvanias. While I do enjoy the process of exploration and puzzle solving on its own it does get tiresome when the reward for said exploration isnt very worthwhile.
The mission pointers did cheapen the experience for me a bit, part of the appeal of metroidvanias is figuring out where to go by yourself. I wouldnt mind it as much if the pointer was much vaguer. An example I can think of is Environmental Station Alpha, it had this kind of waypoint system but they were always placed in the middle of buttfuck nowhere so they only served as a vague direction to go.

Gonna go on to the prime games next, I'm interested to see how this franchise evolved.
