Wow, what an amazing demo!! I have to say I'm super impressed by this game. The sprite work is beautiful and emulates the beauty of point and click 3d games. I think that the combat is super fun! 
I do agree that the blocking system may need to be modified or explained with a more in depth tutorial, as I didn't realize how to block until I was nearly done the demo. 

I can't wait to see the finished project!
