Perhaps one of the most appealing factors of buying Impact is the inclusion of a sample Objective-C project that allows you to compile your Web game into a native iOS app. This enables your game to take advantage of OpenGL for graphics and OpenAL for sound instead of the Canvas and Audio elements in the mobile Safari browser. This solution gives your game almost native-like performance on iOS, and it can be packaged up and sold in the Apple Store just like a native app.
Here are some links to help you learn more about Impact and examples of it in action:
Tools you will need:
For saving levels created with Weltmeister.
For locally hosting and testing your game.
Impact has no IDE dependencies; you can create your games with any simple text editor. I prefer to use WebStorm or PHPStorm since these IDEs, which are made by JetBrains, offer code hinting, project management, refactoring, and debugging.
Impact works very well on WebKit browsers, especially Chrome, but any modern browser with support for Canvas and the Audio tag should also work.
