Hello,
expert in Java programming here. I can implement for you a break breaker like game using as inspiration the provided video. However, your proposed 8 hours deadline is too short for a quality code. Also, because of the requirement of using Jcreator which supports only JDK 6 one will need to use an old computer or a Virtual Machine to be able to develop this. Another potential problem, no modern browser will let currently run Java applications. Obviously I can use an older Windows XP or 7 that will work and has a browser that will let me use JDK 6.
In conclusion, it is doable but it requires more time than you suggested. If you are interested we can discuss in chat the details.
Thanks,
Paul
