Almost 6 years ago I posted my HTML5 Game "Biolab Disaster"[1] and my JavaScript Game Engine "Impact"[2] here.

I have sold about 6000 licenses of the Game Engine since.

Impact was my bachelor thesis and I wanted to release it as open source initially. However, after I finished university I poured a whole lot of time into polishing and documenting it, so I thought "what the hell, I'm going to try to sell it". Surprisingly it worked. Impact pretty much financed all the other projects I've been working on since.

I believe I was at the right place at the right time. Apple just announced that they won't support Flash on iOS and Impact was one of the very few solutions to make (substantial) games in HTML5.

Impact has only received minor updates since its launch. I tried to start with a fresh new version a number of times, but always stopped short - I felt like I couldn't deliver anything worthy of the high expectations people had. Sales have died down slowly over the last two years, partly because Impact is somewhat outdated now and makes some things more complicated than neccessary and partly because there are now very strong Open and Closed Source alternatives in this space.

At the beginning of this year, I finally found some new perspective on what a "Impact 2.0" should deliver and most importantly, the motivation to implement it. It's currently my favorite project to work on. It's a complete rewrite. Simplifying everything with the insights I gathered over the past few years is humbling, but I love it.

My plan is to have 2.0 ready at the end of the year. I'll probably publish Impact 1.0 under GPL then.

Thanks for sharing. I always wanted to ask you: do you also work a normal job or is Impact your main source of income?

Also, I'm excited for Impact 2.0

I'm self employed. Some of my projects (mostly Ejecta[1] and jsmpeg[2]) spawned a lot of contract and consulting work lately. I'm also selling licenses for my games[3] so other gaming sites can host them and the AdSense banner on ZType[4] provided an impressively stable ~$500/mo for the past few years.
