Befriend sound caught me off guard! Haha! The idea is neat, I would never come with something like that. Have you used something specific to allow certain locations for generation?
On the contrary, simple jogging around can be a bit tedious, even with random generation. Maybe, combining with 3-in-a-row puzzler, where friends got to be close to each other or platformer would fit better here? Dunno, and probably that would be a different game!
