Works such as this are very near to my heart. As a developer of collaborative games in emerging technologies including "HTML5" I want to articulate the intense delight I feel each instance I discover others pursuing this strange, new, often difficult, but ultimately vastly rewarding path to success. I found this particular exchange exceptional.
The developers (chatting in-game) were rather friendly and particularly forthcoming about their sound choices for their technology stack which I found to be refreshing. This kind of transparency, at least in this industry, is somewhat rare and is absolutely commendable.
If you indeed enjoyed the experience, as I suspect most did, please continue to support these developers and their work. It is through this process we, as a community, will continue to manifest works such as this.
Do not underestimate the power of getting the word out about these endeavours. A "like" on Facebook. A tweet. A blog post. It all adds up. And we really do appreciate such a priceless commodity.
