Couple of things
First off, great game, well made. I would like to make two points that would have made it better for me. First, the dragon's turning -then- moving was a little annoying. Some people may feel they have better control that way; to me it was slightly more tedious. Also, if the types of breath matched the types of blocks in a more obvious and intuitive way, I'd have adjusted a lot faster.
Even still, I applaud you.
Thanks for the game.
