It was too late for me to realize that I was playing an old version of this game by the time I've finished it. I encountered too many blank puzzles for comfort and even outside of them I wasn't a big fan of the resource management side quest.
That being said, everything else worked beautifully for a presentation and soundtrack that is among the best I've seen in this genre and makes me a little upset I wasn't able to cherish it all the way throughout. It got me hooked almost to a dangerous degree, making me stop as soon as I got to that last screen and the credits.
Maybe I'll give it another go in the future once the complete version is here to stay. Well done regardless.
