Fast Bubbles

This is my first android application made for a school project!
Fast Bubbles is a free game for mobile users.
The idea is to have the player click on the bubbles on their screen as fast as they can. These bubbles would appear in random order and may show one or multiple bubbles simultaneously for a short period of time. The player will have one minute to try to get the highest score possible. Moreover, each bubble shown will have a different colour indicating a certain attribute. Green Bubbles grant 15 points, red bubbles deducts 8 points from the current score and yellow bubbles adds one second to the timer.
Fast Bubbles will allow the player to share their score on social networks, hoping to encourage competition with others to see who can be the fastest. Another feature in Fast Bubbles will be the possibility to change between three different languages, choosing from English, French and Portuguese.
