Great game so far, love it.

I'm stuck in the first region though, and there's no indication how to advance to the next region.

There's a sign pointing to the Yelling Mountains, but you can't get there through just walking on the road.

Any hints or help?

Hey Lifetronome, I'm glad you like it!

Unfortunately the demo version features only what you probably already discovered. The world in Soulash is consistent and changing the region is happening on the background (new region names are displayed above the minimap when you move from one place to another). There will be more regions coming in the proper alpha version of the game, but if you would like to see a sneakpeak I've shared quite a bit of different regions and ability animations on twitter.
