Thanks Chef! I'm glad you enjoyed it :) Thanks for your question.
Last time I saw that people really liked the game, but had a hard time with the UI, which was a shame because we were already working on the new global UI (the one with multi-genre items and quests) and we barely missed the window to send an updated build.
That's why we wanted to be back in this event with that update so it's a smoother experience now.
This demo build also includes things like the Platformer sword , the new currency (Tokens) and other goodies that we added for the intro episode in the newest Early Access Update (v0.4.2).
There aren't any major changes beside the UI, as the levels and story are the same, but that new UI improves the experience quite a bit.
