Just played the demo and I am certainly enjoying it so far. The characters are great, especially the leads (I anticipated liking Alice more, with all her sardonic humor, but it's impossible not to like Anna).
I planned on progressing with the game despite the fact that the grand majority of it will likely be scrapped, but I encountered many errors that restricted me from progressing, which is fine, seeing as you said yourself that this isn't a polished work but just the unrefined beta.
I am thrilled to see where this game goes, and the voice acting is actually quite good! I wish you the best luck.
