I've added some new content, fixed some bugs and most importantly I've implemented the save system in the demo. Currently, it's a little bare bones with just the ability to create(including overwrite) and load saves. I'm going to be adding other features such as the ability to delete saves and for the UI to give context on what's in the save and information such as when it was created. There's almost certainly some bugs with the saving system so if you find any report them on the steam forum or discord.
Below is a changelog with most of the changes though I haven't included everything.
