Thank you guys for playing the demo so far!
I've been working to figure out the issues with the crashing, and I can confirm that they're mostly sorted out now. I've yet to experience a single crash in my sessions testing these fixes tonight, but I'm going to give it another full run before updating the game here!
*Edit: the hotfix is now live! The game should now (hopefully) crash significantly less! I've stopped finding crashes entirely on my end.
I'll increase the measures I took to stop those crashes in a later hotfix today though, just for some reassurance, along with some refinements to iron out some graphical/menu kinks.
*Edit: put out the second hotfix for good measure!
