The sheer quality of AM2R is insane. Seriously, this is a fangame, yet they got so many things right! Samus feels amazing to control, the soundtrack fits the atmosphere and they overhauled so many things to modernise Metroid II while still staying true to it.
However, this latter part, staying true to Metroid II is what hindered my enjoyment with AM2R a bit. There aren't any huge places to get lost in, it's usually very clear where you need to go, because AM2R is split up into so many small areas, which makes exploration a lot less satisfying than Super Metroid or Metroid Dread.
Oh and the Metroid fights are also very awkward, which is kind of a bummer if you consider that you fight them over and over again.
Nevertheless, you can truly feel how much love was poured into AM2R and I deeply respect that.
