Your game is fun, but drag and drop makes it hard. Plus, you need some story so that we can feel more in the game.
BUT
Your game has some interesting content, I felt very interested in the fact that we only have 3 piles and cards can only be superior, this is what I like! The music is a bit entertaining, and sounds help us to understand.
PS : I played without reading the tutorial, and I was like "Bro, wadoaydo", so adding the tuto menu is very great!
