A lot of work went into adding support for Steam achievements using the excellent Greenworks library. This version includes 37 achievements and there are 10 additional ones I couldn’t add due to the API for progressive achievements not being available on Greenworks; the addition doesn’t look overly complex, however I would need to set up a complete dev env for it (right now I’m using their precompiled binaries).

The challenges are not steam exclusive, but they are only tracked right now on Steam (that means you’ll still see when you complete them on any other version, but they won’t be added to your profile).

I also bumped the version of nw.js to 0.20.3 (I think I had to do it in order for greenworks to work). This increased the size of the downloadable packages for desktop quite a bit.

This version also includes some small but important gameplay changes, see this link for complete info.
