I just finished my 2nd game. This one is a test of your accuracy and speed.
Bubbles are floating toward your base. You must defend it.
The more bubbles you pop the higher your score. The more accurate you are the more bonuses you get. Use your bombs tactfully because the bubbles they pop count toward your accuracy so they can be helpful in keeping your accuracy up.

I fixed so that the credits show up. Instead of the instructions now.

I also fixed so that you can cancel out of the login at the end if you don't want to save your high score.
