I'm an indivisual programmer interested in making games and its related technologies. I create applications on this site in my spare time.

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...)
Just released a small game Landolt Wars.
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...)
Live Piano for iPhone/iPad
A simple and easy-to-use mobile piano application.
The movie of the "Delta Strider" (currently unavailable).
I was developping "Delta Strider 2" but the project is paused due to my priority changes (sorry...).
