My development and testing has been centered on Mac + Safari and iOS (iPad.)
Here is the link to my final project:
You click on the sound buttons and the stickman dances and changes colors in response to your actions.
- Works: Mac + Safari, iOS+ Safari (it is formatted for the iPad but will work on an iPhone5)
- Partially works: Ubuntu + Firefox (visuals work, but no audio)
- Does not work: Windows XP + IE (does not support the canvas tag)
This likely works on most platforms with Google Chrome but I have not tested it.
