Hii, This is such an interesting idea and a good prototype to build up on.
I had some problems with the three tiles beside each other, I wasn't able to select the middle field to move to it.
It would be nice to see when the cloud is empty, make it smaller maybe, but the only thing I didn't like in this version is that it constantly asks if I'm sure to do something. It takes away from the gameflow. Other than that I really like it. Good job also on the artwork and music
