Have you played Promesa? It’s a short game made up of vignettes based on stories the developer’s grandfather told him. It can get abstract, but not in a way that makes it hard to understand. It’s a really great meditation on memory and what we pass on to those that come after us. What makes it great, beside the excellent presentation elements, is that the themes come through not only in the narrative elements, but in how the game is structured.
It’s cheap on Itch/Steam and only takes around 45 minutes to play. Try it out if it sounds interesting!
