You might be right, but Kal has been sharing more updates on development on Discord over the last few days, things like the complete rework of the tower defense minigame, and honestly I personally don't think the release is too far off.
I don't know if anything new has been shown about Amelia yet, but Kal has said there will be 10+ new costumes for Anna, and more characters will be joining DnD as well!
