Feel free to check out my “Batman Style” Block Breaker. My 7 year old daughter loves Batman so I made some mods to the game to personally tailor it to her. I’m going to try and add extra lives to the game like some other people did as well as a mute sound button for those who don’t have the same taste in music as my daughter. 
Anyway, it has 3 challenging levels to try and beat so good luck!
