Playability:First of all for some reason the computer attacks very slowly sending only around 6 men at time it gets very boring after a while, however if the computer where to send all his men like normal you would quickly get killed with the troops you supplied to tell you the truth I didnt even finish the scenario one other thing you didnt give any food.
Balance:What I said above basically explains this.
Creativity:The Dam was just gorgeous, a very good piece of work and I like the concept of your dam being broken and getting attacked.
Map Design:Like I said above the castle was good but the terrain was a little less than average.
Story:The first thing I noticed was so many errors in your spelling so many:( it didnt even seem like you tryed to spell anything correctly. The story wasnt descriptive enough either like who was the king of the castle? or give some background on the castle or its people or something.
Overall I think maybe this should go in the free build section.
