I watched some videos, they are pretty good!
However, sometimes the videos seem dull and sometimes you guys sound a bit depressed. This isn't bad but try to perk up once in a while. And finally, if you know someone you really trust, you should invite one or two friends you know (in real life) on your server and they can be one of the antagonists. It would also server a purpose for your serious as well.
Good job you two!
EDIT: Just saw episode 4, that one creeper...you guys should have more views, this is a really good serious!
