I would not recommend this, but it wasn't bad at all. It's mostly because it did have a pretty funny and unexpected ending. I wasn't expecting them to all die. Wait, the bear was okay, right? I love the design of the Tera Eraser. It was quite nice to stand out in contrast to the mostly cheesy animation.
I think the voices need work. There wasn't that much distinction. Wouldn't Newton already be dead? I guess this eraser is a good shot. Of course, in reality, they probably wouldn't even last THAT long.
