I played all of Donut County today, which isn't hard. It's not meant to be a long game. I wish it were a bit longer, perhaps.
I enjoy games that don't mind being a short, focused experience. Gunpoint is still one of my all time favorite games, and it's maybe four hours to complete that campaign. Donut County lasts about two hours, and another hour to go back and get all the little easter egg achievements if you want to do that.
But it got me thinking, and the ideas in it are sticking with me. It's an interesting game, full of gentle pointers toward bigger topics. At its heart it has a lot to say about people who have been pushed to the edges, and how easy it is to push them over.
