It's important to have a video set up to show what type of message you are putting across even if the audio is on mute. On this latest video, you are holding the camera in your hands while spinning back and forth on the chair and generally not looking at the camera.
This, to me, suggests that you are either not comfortable making the video, or you simply don't care. Either way, this puts the same feeling across to me, seeing as you are asking for my (and of course, others) money. I do not feel comfortable in doing so, or doubt that you'll finish the game (based on the video alone).
I'll admit, I only got through about a minute and a half before I turned it off.
My suggestion would be to try and make a video without anyone speaking. Maybe have some nice music, and some screenshots and text explaining what the game will be like.
