Impact
Xibalba Z-Type Elliot Quest Biolab Disaster Create a Game Video Tutorial

Impact is a JavaScript Game Engine that allows you to develop stunning HTML5 Games for desktop and mobile browsers.

I’ve tried four other JavaScript game engines, and this is the first one I’ve used that makes sense (…) Impact is the first truly professional-grade JavaScript and HTML5 game engine to hit the market.

Flexible Level Editor for Anything 2D

Weltmeister Level Editor

Impact comes with the versatile Weltmeister Level Editor that lets you create your game worlds with ease. Whether it's for a side-scrolling Jump'n'Run or a top-down RPG – Weltmeister is up to the task.

All your entities (enemies, NPCs, triggers etc.) can be instantly used in Weltmeister and you can connect entities with each other to create logic chains: find button, open door.

Publish your Games into the AppStore with almost native performance

With the Ejecta Framework you can easily publish your HTML5 Games in the iPhone AppStore with perfect sound, Multitouch and almost native performance.

Ejecta takes your JavaScript source code, executes it and directly renders your game via OpenGL onto the screen. This bypasses the iPhone's Mobile Safari completely and thus avoids some problems that this browser still has.

Your Impact games will be truly indistinguishable from those written in native Objective-C. Check Biolab Disaster and Drop in the AppStore and see for yourself.

With your Impact license you will also get access to AppMobi's GameDev XDK. The XDK allows you to easily create and package native Apps for Android and iOS and provides a lot of cloud services.

Powerful Debug Tools

An easy to use Debug Menu helps you find performance bottlenecks and see what exactly is going on in your game at any time.
