Wat?
That was... Awful. It looks like something you whipped up in five minutes. I mean, the background is just three gradients and one or two basic trees that keep looping. The guy himself is stiff (He never even blinks, and only moves when the snake attacks and when he finds the flower) and from an incredibly weird angle (Next time try something where you can see both his eyes).
The jokes weren't really funny, but part of the reason for that was the delivery, you can't really tell a joke through writing. Especially when it scrolls so slowly, you see everything coming a mile away. Voice acting would have seriously improved this.
Oh, and that bird sound was really annoying the first time, but repeating it throughout the whole thing was just cruel.
