I've checked some of the Patreons posts, and zaaaaaamn, Snats is kinda of too ambitious for his own good, there's ton of new planned characters for the remake that were announced before 0.1.5 dropped(which from what I understood is the first version of the most recent remake) and as of now are nowhere to be seen on the game itself, so they're planning too much ahead and creating content that never was in the previous versions, which makes it take even longer to finally complete the prologue
It's basically "feature creep" TBH, I just hope that by 2069 we won't be getting more remakes(that from what I've heard this is the 3rd or 4th time Snats is making the game from the ground up) and that the game will finally reach 1.0
