THE INTRO:
No no no the mii music continuesssss!!! Ahhhhh!!! I makes the flow of the video flow into each other, making your intor feel like a continuation of your hook, which feels off.
Personally, maybe a bit more hype and a tad more energy would help with the intro (but I am a very hyper bunny who kinda just vibrates with energy when told to sit still so... I am very bias on this). It feels like you are actually "introducing" us to this game, like it feels like:
"Hello everyone. This is a game. Game, this is everyone. Hello all. The game is this."
Even though thats not what youre trying to do. I know youre trying to thank and hype your friend (shout out! Whoo!) and try to rev up the audience into this crazy concept (rolblox can be scary? No way?!) but the straight face, right in the camera stare is giving me video-presentation-vibes.
To break this, maybe think of the viewers are friends, and you're gaming with your friends. Like, instead of being so formal and stiff, let loose and act like you're telling your best mate about this insane thing you just discovered! "You wont believe this dude but shoutout to my friend ____ for sharigng this with me. Rolblox actually has this insanely scary game..." something like that? Not literally, but in essence, of course your own words should be used. I think loosening up will really help! Intors are nothing, theyre like a quick pitch at a friend. Also I'd like to say that the intro should explain what the game purpose is, if its nesscary or needs explained. I have no idea what this game is other than its a rolblox game.
