I just recently played the original game for the first time and I gotta say I think this is a wonderful remake, keeps the same atmosphere, stays faithful to the story and design for the most part, while adding really sick new content, music is also great and visually it looks stunning. Mechanically it's the best feeling Metroid game ever made, Samus has never felt this smooth to control, it's fast paced, flashy, and fun.

However, I have a big gripe, that permeates through the whole game, and that is the actual Metroids, I think overall, they're an improvement on the original, I like the fact that they have new moves and attacks, new designs, and there's some cool new encounters I enjoyed, but my problem lies in the fact that they also changed their hitbox, you can now only damage them by hitting them in a weak spot that is very small, and hidden behind their legs, this doesn't sound bad and overall, it isn't, but the problem is that you encounter these enemies a lot, 40 times to be exact, and they move around a lot, so you'll find yourself just kinda waiting around for them to be in the right position so you can hit them, it slows down the gameplay a lot, and I honestly think if their hitboxes worked just like in the original it would've been much better. This game's original bosses however, are incredible, so at least it balances itself out a bit.

Outside of that though, this is an incredible game and the fact that it's a fan project makes it all the more impressive, it has nothing to envy from any other Metroid games made by Nintendo which is saying a lot because I think most developers nowadays have a lot to envy from Nintendo, really incredible job.
