Marvelously Awesomely Breathtaking!
Pretty damn awesome! The animation was smooth and the action was fast, fluid, and well-done! The character design of the skeleton was really great, and the character design of the goons that protect the temple were also well designed. The story made sense, which is very good, because a lot of the flashes that show up on Newgrounds.com don't make any sense at all.
The ending made me chuckle at the sign, and I would love for Skeleton Jack to actually go there, and for this to become a series, 'cause this was epic and awesome!
