Doki Doki Literature Club is a must-play in the genre. Don’t do any research about it, go in completely uninformed. https://ddlc.moe/

One of my favourites was 7 Years From Now, which has a brilliantly written interweaving time travel storyline and surprising ending: https://play.google.com/store/apps/details?id=com.HirayaSpace.SevenYears

I also really enjoyed One Thousand Lies, because it has a thought-provoking coming-of-age story and completion unlocks a very clear explanation and analysis of the story which contains some cool things you might have missed along the way: https://keinart.itch.io/one-thousand-lies
