So, finished off Samus Returns last night (So spoilers within)

It did a great job of re-inventing the older game (being Metroid 2)

You can see where they took visual cues from each area, while giving it a new look and individual feel.

And the new Metroid fights are incredible

Zetas and Omegas no longer just randomly float around trying to ...tackle you to death, but rather leap and claw/fire acid and lasers at you. even Gammas and Alphas get into the later in that regard

And they've added 2 new boss fights as well

first off, a giant...what I assume is Chozo in design...digging robot.

Diggernaut as the wiki calls it

It just teases you throughout the run, taking powerups, chasing you with its digging impliments and generally being an asshole. Until you kill it, and Samus shots it in the face when it tries to get back up

^so badass

of course, Arachnus returns to give you the spring ball

but the second added boss made me have a 'WTF are you doing here!?" moment:

'Proteus' Ridley

basically...he's shedding parts of his Meta Ridley form in an attempt to show how he got back to normal for Super Metroid

immune to missiles, but not beams for some reason

...and apparently you can counter an attack I just decided to dodge the entire time. Frick

Overall, I loved it, despite geting the worst possible ending by taking WAAAAYYYY too long (first play completely blind. whatre ya gonna do?)

Oh..and the time slowing ability needs to come abck again. SOOOO many puzzles you could make with it
