I was planning to use my own tool, Parser Commander. It is still under development but i recently use it in a game based in the story "Celephaïs" written by H.P.Lovecraft. That game is in Spanish, at least by the moment, but can be played here if you want to take a look:
Play "Where the sea meets the sky - Celephaïs by H.P.Lovecraft" (spanish version only)
The game for this Ectocomp will be mainly played in a web browser, and the sounds will be probably controlled through the javascript "Howler.js" library.
Let's see where this ship goes! :D
