Hindsight says these maybe weren't the best suggestions (I do apologise), anyway just wanted to say I still enjoy the game. Its actually quite reminiscent of " "Beast" 's Castle", an old Playshapes game from way back. The storyline isn't too dissimilar, and the content in both this and that is really nice.
Not 100% sure if the browser version has had any new content in its most recent update, but it definitely seems to at least in contrast to the standalone version.
All the best :)
