Really need an undo button

This game really really needs an undo button, even if it was just like a 15 second time limit or something.

Seriously, when you take a card you reveal hidden information. That means there should never be an undo.
And people should play their moves more carefully. Why not think 15 extra seconds as opposed to enable undo in 15 seconds?

Confirmation, maybe. Undo, NEVER.

Some mobile devices are too narrow to touch right cards precisely. Still, it should be a user preference confirmation option, not undo.

I usually zoom in on mobile (with 2 fingers) when display is too small, to avoid these errors.
