Metroid 64 fan game in development for PC
A Tweet from April 26, 2022 shows a two minute demo of gameplay basics; we get to see Samus running and shooting, turning into a morphball, as well as some platforming. While development is certainly in the early stages, Akino appears to be serious about the project, to the point that he has written a synopsis for the story and decided where it will go in the timeline, taking place before the original Metroid so that it doesn't "interfere with the official timeline." Akino has also said that, while he would love for it to be playable as a ROM, right now it is only being developed for the PC.
