1) Viewporter.
https://github.com/zynga/viewporter. Zynga’s open-source code allows you to get screen size on any device and to scale your game to match. It saves a lot of time from writing it yourself (we know because we’ve used Viewporter and written our own).
2) Weinre.
http://phonegap.github.com/weinre/. A remote debugger that works like Web Inspector, but on mobile devices. A real lifesaver when it comes to tracking down console errors on devices like iPhones and iPads.
3) JQuery.
http://jquery.com/. Why write your own code if you can leverage a library? For things like text animations, JQuery’s very solid. We’ve made a few modifications, and JQuery Mobile now exists, which is better optimized for mobile devices, but JQuery gave us a huge headstart.
4) node.JS.
http://nodejs.org/. When you’re working in Javascript, it saves a lot of time and effort when you can have your client code and server code match as closely as possible. node.JS also scales remarkably well when acting as a game server.

После некоторого перерыва возвращаюсь в ЖЖ. Цель текущего поиска - найти реализации игры типа "Найди предмет". Желательно на HTML5, но подойдет и все другое.
