I can tell that there is a really nice game in here, but there a few issues which prevent the game from reaching its potential. As others have said, the world is done in a beautiful style, but it is very difficult to navigate, especially in a game which should really reward map knowledge. It would also be great to get more information about the different colors and what they do compared to each other. Final small gripe is that I'd love if it was a little easier to tell which direction the character is facing.
As a general concept though, this is very nice and I would be happy to play again in a version with clearer UI elements.
