Some achievements reward them, and you can buy a couple mid game, so they are partially renewable.

Hi lordvuty, are you playing on WebGL or WebPlayer? or the "out of sync" error? For "out of sync", a fix just went live. Please let us know if you are still having difficulty. For connection to WebGL, you may try to clear your browser cache (all boxes checked), but WebGL is experimental technology. We recommend playing on the WebPlayer version for a smoother experience.

[Copied Answer] That is not something i control.... WebGL only allows if the tab is open, but just put this game in it's own window, then it'll run :)

It probably has something to do with your browser or unity plugin. Currently you can't play it on chrome. If you use a different browser, try deinstalling your unity plugin and install the newest one.
