Your striking above middle field
It was short but it was to the point. Which is great, because who really wants to watch a 5 minute long animation if it could be explained in 2 minutes.
Someone else wrote a review saying "The graphics were pretty good! ...and the animation was awesome." I agree. Your graphics are pretty good, they are not the best but we can't expect that from everyone.
I had a bigger problem though. To me the animation style seems to be inconsistent. For example the phone looks different from the man who looks different from the background which looks different to the rockets.
If you ever plan on re-doing this animation I would suggest some updated assets and a starting and ending frame. Loops are good but this is clearly not a loop, so it should have a loading screen with a play button and a closing screen with a "watch again?" button.
