Finally found some time to play this, and, long story short - it was very, very good!
The puzzle design was especially strong, I thought - diverse, inventive, and just the right difficulty for me - logical and solvable without a walkthrough, but tough enough to make me go "A-ha!" from time to time.
I can only imagine how taxing it was to programm all that stuff, but it was definitely worth it in the end!
The writing was also top-notch, with some great humour embedded into the dramatic and thrilling narrative.
And all those little animations, and the highly compelling voice acting, and the nicely contemporary soundtrack, with hints of Ligeti and other wonderful composers of our time... High marks all round, basically! Congratulations and thanks to everyone involved!
