Starting on the new aditions for the hub area
This is how the hub area looks now( in my drawing program, without the characters and what not):

And this is a sketch of the new areas I'm adding to it:

Before now we had a little sample of the three of the four factions: Fantasy Faction - the mostly green area, Robot Faction - the mostly blue area and Horror Faction - the mostly grey area. In the upcoming update I want to reveal a bit of the remaining fourth Cartoon Faction. I want to make every Faction feel different and the Cartoon Faction will be linework based instead of painted, but also it's the only faction that will consist mainly of buildings. Another aspect I want to emphasize for this Faction is a sort of aggressive level of unseriousness, hence the giraffe based architecture. I have a monster you can find in the caves called the Grotto Giraffe which is supposed to be a creature that go fed up with working as a building support and decided it's better to live in the caves. It's dumb, but it's fun, you know?
I want to have different layouts for each Faction as well and the Fantasy Faction will be much more vertical, full of ravines and steep cliffs going forward. That's why I sketched out the tall thin rock wall on the bottom left to separate if from the Carton Faction above. Not sure if I will show the entire height of that wall in the game while it's fairly empty and I get to adding further details there.
