Limitations of HTML 5 implementation on different platforms browsers

iOS

Issues we've encountered:

• Needs user input to start audio (hence the splash screen before the main menu)
• Preload attribute not supported in mobile Safari (so the music is randomly out of sync in the intro depending on Internet downloading speed). More info about iOS/mobile Safari audio limitations on here
• Image scaling issues. Stage resolution (the actual game view) differs from the real resolution of iPad-mini so there are scaling issues with images. iPad-mini's real resolution is 1024x768 and printed stage resolution through java script (excluding the browser search bar) is said to be 981x643 which makes no sense. A screen capture from iPad-mini says though that the stage resolution is 1024x670 (excluding the browser search bar, which is 98 pixels. 670+98=768) which is correct.
• No playing two streams at the same time, i.e. music AND sound effects (grr)
