It seems like the kind of idea you might just "step over" as being too simplistic. I wish I had the time and energy to just explore simple ideas like this to see if I could create a compelling game or creation out of them. I think it takes a child's creativity, earnestness and positivity in some respects, and I'm afraid to say I'm a bit down on the world at the moment.
Shame that no developer takes risks like this anymore, the whole concept was just so foreign, so strange, yet it worked.
