Thanks! Glad you like it.
The dragon difficult: I forgot to rise the HP more than the 50 "testing" points, so it's extremely easy. Plus, run out of time to design a good scenario for the fight (to avoid going behind it and wait the knights kill it for you). Similiar with the skeletons. At first they were impossible to defeat. So I lower their difficult just to make them fair, but I think I made them too easy. Only if you fight them alone, and they outnumber you, they become a challenge.
Thanks again for the feedback. Love your "Limbo" like game!
