… Hammer.js is. My girl suggested building an app for kitties to bat moving colours. A few such things already exist but this felt like a good opportunity and yes it works really well! Check out Soft Paws on my Github – at the time of writing it’s not got unit tests and it’s particularly elegant but using trigger.io I was able to build an .apk!
Sadly trigger.io does not support playback of sound at this time so maybe I’ll have to port to PhoneGap or Sencha? What a shame about trigger.io not supporting audio, though – otherwise, it would have been a beautiful way to get simple games onto Android.
