Short is good. I've always wanted to see some kind of "useful game trailers" that gave you a quick overview of a game—pros and cons, genre, gameplay, story, etc., in a short amount of time. It could be a little longer too, up to three minutes or so is still an "impulse watch" for me.
I agree with Lares that it could use more intro. What is this game? Is it in development, early access, released, old? Is it the developer's first game, or did they do something that I might know about? That kind of thing.
Instead of just showing your logo fading in for the first six seconds, I would show the video series name ("Rocktobot Reviews") in big text, plus your logo, on top of a cover/start screen image from the game you are reviewing. That way you have a little more intro and don't waste those first few seconds. Also, putting stuff in text, visually, is easier and more reliable for people to comprehend than your voice, especially when you're talking fairly fast (which is fine).
Something like this:
Regarding audio: If you haven't already, look up how people process their voice-overs in Audacity. You may be able to just lower the treble a bit and sound like you have a better mic than you do.
In the Kickshot video, I personally would want to hear:
- More specifics about the gameplay. How does it work? You can run and wall jump I see, but you also have a grappling hook and a rocket launcher? A few sentences about how that basic stuff works would be nice.
- How much content does the game have? 10 levels, 300 levels? Can you complete it in an evening, or is it a 40-hour game? Is it replayable or a once-and-done deal?
- Price, platforms, and where to get it. I didn't realize until now that Kickshot is free-to-play. In that case, does it have premium stuff, or is it actually totally free? Otherwise you could just say, "It's on Steam for $15", or whatever. Also if it's on Itch, Humble, or GOG. And is it windows only, or Win/Mac/Linux? I'm PC master race all the way, but a lot of people probably care if it's expected on Switch and other consoles (and probably if it's playable with a gamepad or keyboard and mouse only (or vice versa...)).
