Neat concept, the right click menu impedes gameplay however. You can do this through unity by going to File > Build Settings > Player Settings > Resolution & Presentation > Web Player Template and select the no context menu. It will help a lot!

Good fun, liked the cool dragon anims and the opening cutscene. Could definitely see more of a story presented through the cutscenes further on. Strongly consider the ability to launch peasants... :)

Have a good one.
