Mandagon is a short but lovely freeware game. It’s a platforming adventure about a little totem. There are no deaths or failures, only the story.
I was truly impressed by Mandagon myself. It’s so pretty, atmospheric and smooth. It’s objective is to open up the door in the middle by activating certain objects around it. The gameplay is simple but it has some extra dimensions that would be good enough even for a longer game.
There is only a few lines of text in the game. I believe the experience can be felt through the atmosphere and imagery alone. There are definitely similarities with Journey.
