This is a little html/jquery game I've been working on for the past two years, on and off. It should work in recent Chrome/Safari/Firefox/Opera. jquery.animate-enhanced plugin converts javascript animations to CSS3 which is very smooth where accelerated (like on iPhone/iPad). There's also a native version for iPad (free and paid, a lot more levels) - the same web app runs in UIWebView. Check it out. Email me at [email protected] if you'd like promo code for the paid iPad version.
