After much fiddling, the Demo is ready for action! You can now play it to get a general feel for what the revamp looks like!
...Yeah, I don't have anything else to say besides that. Enjoy! ːsteamhappyː
[EDIT]
After concerns raised by user Azzul, I can't seem to find the "Demo" Button on the Store Page. I've uploaded it to Steam and it says that it's been uploaded, but for some reason, it's just not showing up. If this isn't just a problem on my end, then it may mean that you can't play the Demo until the Full Game is released. Which is dumb.
So, December 23rd is the moment of truth. See you then!
