Late review lol
Okay, I agree with you that Pivot can be decent for making videos, but, no offense, you need to improve a lot if you think Pivot is going to make it on here. You can look on YouTube and there actually are decent Pivot videos, and buddy, they're way better than this one. There's no plot, needs to have more frames for better fluency, needs to have... erm... better looking obstacles, and it needs to be more interesting overall. Sorry my review sounds so negative, they usually aren't like that. =P Anyway, good luck in animating.
