Wow ! It’s quite impressive ! I really love your work ! The idea and the realization. What is the development time of such a website?
My feedback for improvement : First I wonder if the quality of the mountains could be improved a bit. (Some polygons have weird UV textures/ It’s very low poly as well). Then, instead of big arrows, could you find some items (small rocks, swamp plants, semi-submerged ruins…) to place between mountains to block and guide the visitor in a more natural way ? Of course, you should be careful that this does not impact performances too much. It might be fun also to imagine what happens if the user hurts the mountain too often, maybe damages the boat, sinks and takes the visitor to a more hidden place on the site ? Well, it’s just an idea. ^^
