Beautiful design but needs some refinement like the option to tap instead of just drag the cards to their place. Also needs an undo button in case you make a mistake when you are playing casually. Some sort of "fireworks" when you win would also be a nice touch.

-im ok with no undo button (can't cheat :)-just learned about shake it for new game :)-took some getting used to with the new graphics, but now I can't play as fast on the desktop with "cards" :(.... need online version for safari or firefox :) and ability to sign in across devices- brilliant fresh design, great movement during game

Well designed. Minimalist. Does everything that the developer said it would do. + more. For me I like looking at an old game in a new way. Playing it is familiar and very new at the same time. It is challenging in a way I like.

I congratulate you for your great update, good job. However, now the app does not work well after the update. I enter a game and when I want to go "backwards" it hangs up. it does not move anything, neither up or down nor for one side or the other. I liked the previous version better. They should look at all the flaws before launching an update!

I recommend change the Lefty from Off or On to L or R. That way L is on the left and R on the right. It will make it easier to switch between each.

Nice visual style.Please add more color customization options and some minimal sound effects?
