I don't really know what to do with this game. I think it's mysterious in a good way, and I'd love to recommend everyone to try probing at its weird secrets. But it's also not a very strong game in the mechanical sense. In fact, it's downright hostile in some ways. If you happen to have played Yume Nikki and enjoyed it, you might find something to like here. Otherwise, it's hard to endorse Strange Telephone for much other than its well-crafted visuals and audio.
I’m a bit disappointed with Strange Telephone, to be honest. It had a promising start, and I was interested in seeing where it all went, but after so many repeated trips to the same not-really-random worlds while floundering around trying to figure out how to progress, I just got tired of it.
