Surface Hmmmm...
Hmm... not too sure on this one. I liked the theme but was somewhat confuzed with the abrupt ending, though i expect this will be clarified in future episodes. Eventually the voicefe of Nathan and his thoughts started to become corny and seemed to go on with the puzzles a bit too long, it was like he was constantly stating the obvious. The animation i wasnt too crash hot on either, i thought your drawings were good but the actual animation seemd more like a series of comic frames rather than an animated sequence.
Overall, not a bad flash. I like where you are heading with it and i think that if you improve your flash skills just a bit and reduce the amount of speech, it will be tops. After all, the audience isnt stupid and sometimes its good to let them see the symbols make the inferences themselves.
Keep up the good work.
