Release ImpactJS Game Engine - $ 99

Today was the release of Impact JS , a two-script engine that, in conjunction with html5 canvas, will allow you to create games. An example of such a game - Biolab Disaster

A little upset the cost of a license - $ 99. But I am sure that free alternatives will appear in the near future.
