The visuals are amazing! I love the idea behind it and it works so well.
But I had some difficulties with the gameplay. In the first run I just walked through the forrest, didn't encountered any npc's and just went through the gate. And in the second run I tried to play it a bit more like I thought it was intended to be played. But I never really felt like I needed to change the worlds. For me it would be important to improve the level design. It should be clearer where you can go and where you should go. But the idea itself is pretty cool :)
