The developper seems to have lost interest updating it, too bad, it was promising.
Thank you for your interest and sorry for the long delay on the update. I've changed so many things since v0.15 and I wanted to test them all out before releasing an update. Unfortunately, the more I postpone it the more stuff I have to change and fix and test.
Having said that, I plan to release an update before new year. Whether or not I'll succeed is another question. Either way, if you'd like to check out some of the changes, take a look at the online sandbox: http://dls.makingartstudios.com/sandbox/wasm/
