Wow, I suffer from the same problem all the time!
Well, great flash. The idea for it was great and classic; not to mention that the animation for it was smooth and flawless. The methods of attack(opening), were quite nicely varied--though, a few more would have made it more satisfying. (i.e.: chainsaw, compactor, H-bomb...) But like I said, the idea was great, even if not completely original(hence classic, but oh well). Keep it up, ya did great!
If it had to be in list form:
Graphics: 9.5 (main character as stick takes a smidgen off for design)
Animation: 10 (I've seen smoother, but excellency isn't graded on a curve!)
Sound: 10 (Fitting music, and I'm never usually picky about quality)
Plot: 9.0 (Plot doesn't always come in WORDS, people!)
Amusement: 10 (Personal Note: I hate trying to open things. I've only opened
cereal boxes over the past ten years by decapitating them.)
