@Yudontno new I saw your channel. It has only 14 videos. Only one video has crossed 1.2k and that's because it was short. You need to be patient and take time to create more long videos. I also notice that you are creating long videos which is good in a way, it helps increasing watch time. So continue doing that. At least create 50 more videos before drawing any conclusion.
If you want to get into suggestions of other videos then identify other top videos in your niche, make similar video of game recording, copy the title, description, hashtags and tags and upload it in your channel.
Try to match the thumbnail too. But do not copy it exact. Just make the colors and fonts same.
Have you used Tube Buddy yet? If not then it can help you with this.
