It's called "walking simulator"One thing I'd love to see, that I don't think has been done yet, is a platform game that is purely an experience — no baddies that kill, no spikes, no deadly falls (okay maybe deadly falls). It's something I plan to have a bash at myself one day, but I just don't have an idea for a theme yet. I suppose we're wandering away from games and into "art", but I think it could work.

And yes, some people consider it an art, some people don't consider it a game.
It would br curious to see something like that on Spectrum but it definitely needs to be good and original at aestethics.
