So Math Ball is finally close to beta-release! 

In this update I have:

• changed the player from a white ball to a red ball with a face, with expressions!
• created a new logo for the game
• finished the upgrades menu
• finished the settings menu
• polished the game
• fixed some bugs
• etc

Give it a try, it's playable in the browser and it's free. 

I would love to get your feedback to further improve the game.
