@Truth Eternity do you play Journey (or Sky)? That sounds like Journey. Not exactly, but it would fit into a genre with Journey. (Which is the best video game ever, so far.)
I think a few people here are making video games. I'm one of them.
Just because your idea is so special, and because I've been in the art business a long time, I'm going to caution you not to be so open about your artistic ideas when discussing them on the internet. Be vague when describing it to others, and then set goals and make the idea happen. <3 Best of luck. I would play that game a lot.
PS: For the record, most of the members here are not the type to steal ideas. It is a public forum, though, and it is a good habit to be vague.
