I had a chance to play the demo round and it was extremely performant - well done. The only thing I'm not sure about is that on the first click of each piece it automatically orients itself to the final orientation as expected by the puzzle. Is this an "Easy / Medium / Hard" setting? Otherwise great!
Yupp, it's on my todo list to give users the option on how difficult they want the rotation to be. So far I have users that want click-to-rotate and even no rotation at all.
