DragonBox Algebra 5+

We love this game because it's fun and you don't realize you're doing algebra. We've had a couple glitches where the sizing of the game doesn't line up with the touch screen on our computer, but if we back out of the app, it resolves. We'll be checking into the other levels for our younger children and future algebra levels once we finish this one!

Requesting a refund - the mouse clicks don't line up with the cards, so you can't actually operate the game.

Clicking on the box doesn't do anything. Clicking randomly 97 times around the box sometimes works but makes the game absolutely unplayable. [Attempted on two computers and a touch-screen. Same issue all around]

Help, I can't figure out how to use this?
