This lacked creativity. The shame in it is that you set yourself up with an interesting concept - Goat vs Plane. You failed to capitalize on such a unique idea.
The classic cat and mouse scenario could've worked well. I was looking forward to some witty traps from the Plane and some clever escapes from the Goat. Instead, the Plane just rams the poor animal a couple times, which translates into extremely bland slapstick humor.
On a good note, you really made good use of sound effects throughout the flash. They were all consistent and had that cartoony feel that went well with your artwork. Additionally, I enjoyed your attempt (deliberate or not) to emanate the old Roadrunner cartoons, both through the sound effects, and the artwork/animation. Nice job on that! So overall, it was a decent flash. I just felt that it could've been more elaborate.
