listen
that’s the best classic 2d metroid game of all time if not the best 2d metroidvania of all time

great plot twists
amazing mechanics and controls
amazing bosses and tons of enemy variation
good atmospheric soundtrack without reusing half of past metroid games
a setting and scenery that’s eerie as hell and the stress and danger caused by the emmis makes it even more effective
backgrounds are extremely detailed, they foreshadow some bosses, show how animals live and react to other animals or bosses and the background can give you hints
the tutorials (through text and level design) are superb this time and teach you all the things even the hidden mechanics like the charge jump (is it called like that? you hold the charge beam and do a flip by jumping, it’s like a beta screw attack)

some people might say the emmis are repetitive in how you defeat them but i never considered them as “bosses” but more like moving / living hazards and getting finally rid of them feels way too satisfying cause you’re free to explore an area without the stress they cause by hunting you

easily full score, best 2d metroid, maybe best 2d metroidvania

replay:
i beat this game on hard
without energy tanks
without additional missiles
and without space jump

best game of all time
what an experience
