Um...
I know you worked hard on this thing, and I commend you for your effort, but I need to address a few things:
1. No sound effects for the crashing, bouncing and landing. It doesn't even give us the impression that it's supposed to sound real. All we hear are voices.
2. On the subject of voices, the voices sound pretty emotionless.
3. I know that the entire video was supposed to be like a cliffhanger, but it could've been done a lot better - screaming throughout the video destroyed it. And what's more, the 'Oh look, we're home!' was not resolved too well - it sounded like someone saying 'kthxbai' after his submission.
Please, polish up those aspects, and you'd do well with your submission. It'll be nice to see this remade in future, and I love the idea.
