Updated Live Piano for iPhone/iPad to version 1.5. This version brings limited Retina support (app icon and some buttons) and experimental super low audio latency for iPad 2+. Let me know if you have any problems.

I've been struggling with HTML5 for months to make future browser games. Actually I don't like HTML5 much. It's sort of a mess, especially on JavaScript functionality (see "The Trouble with JavaScript") and many many and many browser dependent issues. There are plenty of bugs on ALL browsers. Here is an experimental game I created (incomplete, IE9+ or a modern browser is needed). Looks not bad, but it required very hard work.

At this time I recommend using game engines like Unity and packaging as native apps if you want to make games. As for me, I need to use HTML5 for 2D Driving Simulators (far more difficult than this experiment...)

Wrote some notes about 2D Driving Simulator on Google Maps.
Sep. 3, 2011

Bad news: Google has announced they discontinue the development of Google Maps API for Flash. I guess my flashes will not be affected within one or two years, but I need to rewrite them using JavaScript at some future point.

I will try to keep Google Maps versions working, but sorry if I can't.
(I'm getting busy these days...)
