If you've played the critically acclaimed Papers, Please from indie developer Lucas Pope, you are probably waiting for his next project, Return of the Obra Dinn, with a certain amount of eagerness.
That game is far from finished, but the development process is far enough ahead for Pope to deliver an early demo. You can download it by following this link, but heed Pope's warning:
"This is a very early playable build. There's not much content
and it hasn't been tested. Progress is not saved. Quit and re-run to restart. Join the devlog or find me on twitter for comments and suggestions."
