Decent animation, with a but...
Well, I don't know why people are bitching at you about the backflip and kick animation... I trust that you didn't "copy" it. Even if you used a video for frame-referencing, this still isn't copying, it's rotoscoping, which is a legitemate method of animation. True, it's better to use video or film footage you shot yourself, but kids animating out of their houses in their spare time can't be expected to do Crouching freakin' Tiger, now, can they?
The animation for the rest of your show was merely mediocre. I say this because I care.
And as far as the humor goes... I didn't laugh once. Seriously, not one time. I didn't even crack a smile. I would venture that one has to have played this game to get the jokes or whatever. However, I suspect that even were I a fan of the game series I would still weep silently inward at the attempt at humor contained in this piece. Sorry, but this is as true as I can call it.
By the way, do they even have marijuana in England? I'm guessing they must, but that you've never actually smoked it. I live in the state of Oregon in the United States (it's on the west coast), and here in this part of the country every man, woman, child, and mammalian pet smokes pot multiple times per day (this includes myself). Oregon's biggest (illegal) export is marjiuana, with the (much more legal) export of trees as raw lumber close behind that.
But I stray from the subject... you have made a common mistake among drug-novice animators here on Newgrounds, which is one of your characters hallucinates colors and tracers as a result of smoking pot.
There is no such effect from smoking pot. Really. Try it some time and you'll see what I mean. If you want colors and tracers, try LSD, mushrooms, mescaline, or some other form of hallucinogen. Certain disassociative drugs can also produce similar effects. Even staying up for several days in a row on crystal or crank can cause hallucinations which may include strange colors, but will more likely be peripheral manifestations of paranoia in the form of "shadow people" or some such thing.
But not pot. Pot gives you no tracers and no colored designs.
Oh, I'm sorry, you fellows spell it "colour" over there, don't you? My appologies.
By the way, why the hell did this take you a year to make? Jesus God, man, do you draw like two frames a day or something?
