Not really a good game, sorry.
We've seen and played exactly the same game 1.000 times before, it's always trial and error with the construction parts. Yawn...
Can't understand why kong gives such a game badges and even a card. There are so many games actually deserving badges!
All too easy. On Lvl 22 just find the "sweet spot" where the ball moves up and down in a vertical line so you dont have to move the paddles.
