Cool
Pretty funny flash - I liked the style that it was done in, you should make continue making things in this style!
I have a mixed opinion on the sound issue. All the sounds and music very well done (especially the dragon laugh at the end) except for one thing - the laugh of the goblin. It was incredibly grating and annoying, and it made my headphones do a screech whenever it came on. So... consider toning that down a little.
Also, excellent animation on the dragon.
Nothing too fancy, but it's done well and it's entertaining. Continue improving, I look forward to whatever you make next.
