That's a difficult question! I usually estimate about 20~25% of the content is done in this demo. This only a rough estimate though! I'm currently focusing on the chibi BE sprites which will be the target of the next big update (among other things). I don't have a clear date for the update or for the full release sadly, but I'm hard at work! As soon as I have a release date I'm confident in, I'll be sure to share it on Itch and twitter and Patreon, and everywhere really ^^
I also have an FAQ if you'd like to check it out:

But yeah, thank you so much! I'll do my best ^^
