We are currently searching for people who are familier with Lost Valleys system and who are interested in designing a map. Here is an idea of what we need. We just need some direction i.e Where can't the player get to, what does he need to proceed, where is the boss dungeon etc.
So, for example if you look at the map below, we could say the green part up the top is blocked as is the right. You travel far to the left and find a dungeon, you get an item. Which help you unblock the right passage in which you find a dungeon and fight a boss. Once the boss is dead the blocked area to the top is removed.
