As I mentioned in the blog post, we will have a new version of the game which is open-world, it will include (hopefully) three new monster girls: a fox, a sheep, and a lizard.
Well, we will be focusing on the plains for the next few builds. It is the biggest biome in the new map so it will need to be filled with events and hidden items and story content. After that, we can look at other biomes and creatures.
