Idiots
To all the retards below me if you look at the Author's comments the FIRST THING IT SAYS is that this is a beta version. Which means that it's a work in progress!!! (just in case you don't know what beta means)
As for the review, as many of the people said it has some problems mainly the invisible people and falling through the floors but besides that great animation and concept. Can't wait till the finished version comes out.
