New Save Data
Before, all of the save data was stored in a single file. This made it tricky to get specific information that would only be visible in the loading screen, like your world's name. As of right now, the save data is put into separate files and with a screenshot as well. This makes the new loading window look very nice.
Preparations
Development for some features have started but are not ready yet, like:
A photo mode. A camera with more motion, to get that perfect screenshot!
Pier and bridge objects. Build a foundation to build 'on water'.
Controller support. This might sound weird for a town builder, but I like my games to be playable with a controller as well.
Did you say Demo?
Generating the just the right worlds, building cities of your dreams and sharing screenshots with the community is what Mini Worlds is about and the demo will have it all. Not all features and buildable objects will be available in the demo but it will give a great sense of what you can create in the full game.
