Focus Pocus - attention game for PC

Focus Pocus was designed to train your brain in a pleasant way.
You are the only numbers hope!
An evil witch captured them with a magic spell and now they are being held hostage.
The only way out is over a cauldron with toxic boiling potion.
Your role is to help as many numbers as possible to escape.
Use both hands!
With one hand help the floating number to avoid the poisonous green bubble.
With the other hand, press the key on the keypad, corresponding to the moving number, to free it.
Lives
You start the game with 5 lives (the bottle on the top right side of the screen).
The lives are lost in 2 ways:
- the green toxic bubble hits the floating number
- you click on the wrong keypad number
Extra three lives can be received if a short rewarded ad is watched.
Score
With every freed number you receive:
- 1 point if game difficulty is easy
- 2 points if game difficulty is hard
Game

The highest score is saved in the game.
Save as many numbers as possible to beat your highest score and improve your focus.
