To make it less add like, you should remove any references to money:
yet must be purchased if you are an individual (or team) who has made over $5,000 from using Construct 2.
need to add content on what makes Construct interesting...talk about HTML5, talk about system requirements, talk about plans for future builds, talk about that it is a work in progress and current status, describe the event system. Should sound like a historian wrote it.
Edit: See game editor for an example...
