Tbh, I've only watched about 30s of this video and the one before it, just to get a feel of the video so take my opinions with a grain of salt.
- The video performed better because the game is currently trending, so its going to do better in the gaming sector as lots of people that arent necessarily "fans" of this genre are still watching.
- The editing in the intro (first 30s i watched) for your repo video is much more engaging, it explains brefily what the game is about whilst keeping my engagement up. If I had more time on my hands I would have watched more of it for sure! This intro compared to the backrooms video is night and day, the backrooms intro is good stylistically, I like the previous and continued segment but it felt like it could be executed better. Im not an expert by any means but as a viewer, when you throw previously on, I expect it to be a video that requires/wants me to watch the previous video. If im interested in backrooms and your content specifically then maybe id go and find your video but as an average viewer this is a bit of an engagement turn off.
- The thumbnail is also better for the repo video than your others. It catches the eye more and uses vibrant colours whilst also showing aspects of the game that are important. Your other videos try to do this but sometimes dont capture it properly, like your backrooms video for starters, the help is way too short and the thumbnail is a bit dark, doesnt stand out to me on a home page.
Hope some of this helps, I focused more on why its better than previous rather than direct suggestions to improve this video. When I get some time im happy to help suggest some things to make your repo video a little better too! ❤️
