They did Human Resource Machine, which is a pretty difficult low-level programming-based game, and 7 billion humans, which is a similar low-level programming-based game but incorporating multi-threading concepts.
Neither are super accessible if you’re not into programming, but if you are into it they’re both pretty awesome. I finished Human Resource Machine a few weeks ago and have made a start on 7 Billion Humans, so far so good.
I also played World of Goo and Little Inferno back on the Wii U lol. Very unique games with heaps of character.
