Humble Bundle key redemption is awesome again (mostly) but the games are kinda meh

Great indeed. But I wonder what motivates people to do something like this. The game’s obviously more a pop-gaming-art-collage than gaming, isn’t it? I can’t decide if the people who made it really wanted to make a game or something else. And if it’s something else… is there a market for it? And if not… how can one afford to do stuff like this? I guess you really have to be an artist.
