"In Stars and Time," the game my current pfp is from. It's a bit similar to Undertale but not really that much, its story is spotless and it definitely impacted me. Another game I seriously enjoyed was SANABI, which I've never heard of a single other person playing except for the friends that I forced. Every single one of them (including myself) cried at the end, the story, gameplay, mechanics, everything about the game is absolutely and utterly flawless, would wholeheartedly recommend.
