Fun and easy to understand and take in hands. Amazing.
One thing I have notice is that my score does not seem to get saved and is always 0 on the menu. And I don't understand what is the "earn more time" for (always 0 also). Normal maybe?
Correct, as of now, your score is not saved. Each time you beat a minigame, you earn 3 seconds more time. If you watch the corner you will see a “+3” appear when you clear a goal.
