As a matter of fact, the game's been developed with mobile controls in mind - with the release of the full game, we will probably opt to make a build for Android and iOS as well if we can figure those stores and the legalese surrounding them out!
Thanks for the suggestion! We originally did, but performance was an issue - we're not updating the demo any further so there's no point in rewriting this particular version to make it playable in the browser, but we could look into it for the release!
