Hi there!
You might have noticed that the demo is no longer available for download. I've been working on the new and updated demo with all your feedback implemented (fullscreen UI controls, performance improvements, reworked guide and much more!) and this updated demo (v0.2) will be up on the 19th along with the game's upcoming Kickstarter!
Consider giving it a follow if you'd like to support the development of the game :)
