After a few days struggling I finally understood how everything works, how a new app can be created and ready to be installed in my watch.
To minimize the development time, and yes, that's why we're using Open Source software, I took the liberty to copy-paste and modify the Pong's code, slightly :P, to be transformed in a BreakOut clone (thanks Frederic).
It's not 100% ready for primetime (need to destroy the bricks), but I see progress, still, needs more work and I do it when I have time.
If you want to look at it and have your eyes covered with blood
Go to my personal REPO and behold "the BrickBreaker"!
Isra-El awesome repo
You have been warned, proceed by your own risk...
On a serious tone, I forgot to comment that I couldn't found a place in the Forums for "BangleJS projects" in progress, there is one but I think is more hardware oriented and not sure where can we know that someone is working on something that maybe we're working on, i.e. is there any other BreakOut effort?
Thank you for your time reading this
