basically its a math, vocabulary, and geography learning game for kids.
you control a little plane and move it towards the right answers.
the game contains a short "story" mode and after that, also a challenge + a infinite mode including global leadboards for on/offline play.
because you can either play with keyboard, mouse, controller... with up to 4 players, it could also be good when you hang around with some friends!
(to see them fail at the easiest questions :D)
the internet is full of free learning games so the price of currently 8,99€ is a little excessive.
on the other hand, if you have small kids and want them to have something to play on your account, this might be a good choice.
