This has a lot of potental. I liked the voxel graphics. There's a few problems though - the text for the quest from the King went way too fast for me. I think it said find 5 warriors with white skin but I didn't see any - hard to tell them apart. The control is a bit sluggish too - I had to click multiple times to get my guy to go where I wanted.
Everybody looks the same - maybe give the different tribes different head dresses or something.
