Almost mechanically sound!

Ok! Many mechanical improvements.

You should be able to play the hand that it deals all the way through. The only mechanical thing that needs resolving is dragging of stacked cards that shouldn't drag.

I don't believe you will be able to play those cards and they should snap back to the original location. Time will tell - I am only one person.

Give it a shot and let me know what you think.

Constructive feedback is always appreciated.

If you don't already have a key, let me know. Not everyone will get a key, I feel I can open it up to a good handful of people though.
