First of all, the art is so unbelievably pretty! Especially the queen's sprite - I just love her design so much! And the snake looks so intimidating!
I also enjoyed the story so far. I'm interested in what actually happened in the kingdom and if the shadow is really not trustworthy. I'm looking forward to the rest!
The timed attack was very surprising, but a good addition! Though I think they're a little too fast >.<
Interpreting the theme as "abandoned Queen" is also a very intriguing take! That's what first drew me to this game^^
Sadly there was no music though... I think a mystical tune would have been perfect.
All in all, this is a great demo! I'm looking forward to the finished product! :DD
