As said in the comments:
There are already a couple of these videos, with nice music and such.
Overall better executed.
Though it is nice to see you are having fun with the physics.
You can also fakekill them infinitely by putting the value behind fakeKill at -1 if i am correct.
Not too sure though. :)
I hope you aren't getting too sad about these thumbs down's on your video.
It is not really the most exciting video to be honest and people tend to just dislike it then.
And still the fact that it has been done before so many times.
But make videos of what you like, other people might see it and see what cool of a game Blockland is due to your video. :)
