You could have put music

I think it would be good for you (if you want to get more into animating) to look into the 12 principles of animation (video about that below).
These could really help out for physics in animation like this if you want it to pop more.
Sound would help too in making it feel more realistic.
Love how you used portal though to test out animating physics!
Keep up the cool animations dood!

The animation itself was decent, and very fluid. However, there's only like two lines of text in the whole thing, and even then, BOTH lines have spelling errors, and are typed in a really generic, and boring font. Also, I think this animation would be way better if there were music and/or sound effects added to it.
