Alright, so basically when I review channels, I like to separate them into technical quality and content quality.
As far as technical quality goes, your video quality is good; don't listen to people who tell you 720p is still bad. The sound was LOUD. In fact, this is basically a music video. I hear no zombies, shooting or explosions and only a snippet of you in the beginning. I guess, that can get a pass since all you wanted to show was getting to round 66. Also you need end cards, they are used so people can see what to view next on your channel.
But going into content quality, it seems as though a bit of post commentary (when you commentate after you play the game), about how you got there, any close calls or anything would help your video a lot. Think of it as this, if I watched this video of you getting to round 66 and another guy's video of getting to round 66, what makes yours stand out?
So yes, your video was interesting and short, which is great. But if you're going to put in the work for daily content, it's best to use that time working on your skills as a commentator.
