I've not seen many RPG maker games mentioned here, so i'll do my part.
These are a lot of my favourites through the years:
To the moon
Finding paradise
Oneshot
Celeste
Omori
End roll
There are also a lot of them that i've not played but i've watched full playtroughs of, like IB, Hello Charlotte, Lisa, ... and most recently The coffin of Andy and Leyley
One game i would also like to add is Rain World, which is a 2d survival platformer, a bit challenging, but i would argue it's also a "metroidbrania" if you know the genre, games that have knowledge as gates rather than keys or power-ups like metroidvanias. Some notable examples are Outer wilds or Return of obra dinn, who others have already mentioned
Woops, i've left Celeste in while re-writing the list, that's not an RPG maker game
And i didn't know about the sequel until now, that's a shame
