No expected date yet. I'm currently working on polishing up this first world and the game's overall mechanics which will be released in a new demo when done. Once the basics are fully complete I'll start chugging away at the other 3 worlds I plan on making. I haven't had a ton of time to work on Candy Quest as of late, but I'll be getting back into it really soon. Thanks for the kind words and asking!
Edit: I'll also likely make some sort of big update post soon with what my plans are and what's currently done/being worked on.
