100% agree, but I had a different thing in mind for this project, since I'm more interested in how to create a "frame" to support minigames from anyone using phaser, than to make a polished collection myself,my choice was to add more minigames instead of polishing them, so the quality of the product suffers from it.
Regarding QA I'm wondering if I can implement something to help the process along the way, I already saw some state problems that could be checked automaticaly... ummm
Thanks a lot for bring the subject of testing :)
