Used to play these all the time and have a big list of them, but lost it. Top of my head:
RPGmaker games are what you are looking for. Yume Nikki, .flow, LCDdem, Answered Prayers, Middens, Gingiva, Where They Cremate The Roadkill, Space Funeral, Earth Birth, Ib, Remnants (by June Flower), Labyrinth (by June Flower), OFF (sic), Jimmy and the pulsating mass, Solitude, Someday, FILAMENT.
Escaped Chasm and Dweller's Empty Path by Undertale luminary Temmie Chang are quaint, though might be too vanilla. Penpals is widely hated, but I thought it was alright. Personally didn't like Wadanohara, though I have admit it looks pretty, but you might enjoy it. OneShot (by Future Cat) is very cute and also recommended. Toilet in Wonderland is a more whimsical take on the YN format, but I love it.
There are more, but I can't recall all of them. vgperson has been translating Japanese RPGmaker games since forever, and you can find a ton of interesting ones o'er there: https://vgperson.com/games/
Hylics and Hylics 2 are in the same vein. You might enjoy Mason Lindroths other games too.
LSD Simulator is recommended and a big influence on a lot of these games. In that family you should take a look at Soup09 and Garmoniums. Parasomnia and singmetosleep (sic) are particularly awesome.
Similar but different games include Crypt Worlds, Bernband, Dujanah (by Sluggish Morss creator Jack Spinoza), OK/NORMAL, and PANORAMICAL. Kitty Horrorshow gets a special mention and you should absolutely not sleep on their many releases.
There was also a very interesting PS1 Japan only game that is the best Twin Peaks inspired game ever made ( definitely better than D3), but I can't recall what it was called. Maybe someone knows what I'm talking about.
