The constant text effect is offputting. Don't do that. Either do a simple fade in/out, or change up the text effects a bit. Personally, I'd go with the former.
Also, simple white over the game background is difficult to read. Either do interstitial text on solid background, or add a stroke/shadow effect to the text to make it more readable.
Unlike other commenters, I like the custom colors announcement. Even in as simple a game as this, customization is often attractive. Only mention it in a single text overlay, though; Maybe headline-subtext format. Make the text short, punchy, 2-3 lines, max.
Combine the 2-player text with the explore a new world text. The PvP lines work as a separate bit of text, though. Also, avoid "Metroidvania". Those who know the term will recognize the style, those who don't will be confused.
No one cares about cameras. Controller support is a worthwhile mention.
Hand-drawn, who cares? The images will speak for themselves, or not. 60 fps, likewise; Those who care will see it for themselves (if the video itself is 60 FPS), most won't care.
No to Dynamic HUD. Show, don't tell. Same with movement options (crouch, backpedal, wall jump, etc.)
"Let nothing stand in your way!" Decent text for the movement section.
Layered animations - NO. Weapons and gear you can see: Find a better way to say it, but this would be a plus in my book.
The game development tutorials section: NO. Yes do them, no don't mention them in the trailer. Tutorial videos which feature your game should be *additional* means of generating buzz and interest, not a "feature" to be advertised. Cut this whole segment, and your video will be a minute or less, which is easily within the attention span of your average internet surfer.
The slo-mo section at the end, it looks more like lag than slo-mo; In the main portion of the video, the animation looks fairly smooth, but here it looks like powerpoint. I'd ditch it entirely, or replace it with something memorable, perhaps humorous?
On the outro bit, have a few bits of info to look for more information, a webpage address, twitter handle, etc. This is the part where you'll want what they call a "Call to action", where you ask your viewer to do something: click a link or read the description for more information; If the video will be purely on YouTube, this is a great place to use annotations to click on. Ensure that it still looks good without the annotations, as they don't work with mobile, and you may want to put the video up somewhere else, as well.
