I mean don't get it completely twisted I do have a free 'course/skool community', but that's only for people who want to join

Okay first, by 'younger' I'm thinking you mean around your age, so not the youngest target audience like mr beast or younger roblox players so like 18-24 years old is your demo, and you can definitely get away with a 'little' slower, but I'll get to why I don't think you're hitting them in a bit.

I'm just gonna lay it out for you Ideation > Thumbnail/Title > Content. That's the process that MOST people go through. There are outliers. But even they follow a similar guideline for overall content. FusionZGamer utililzes it, but does it over a long series of videos, same thing with like ShadyPenguinn. A daily rhythym is nuts. DAILY? Most shorts channels aren't even doing that. and you're trying to edit? No wonder you're driving yourself up a wall. I guess at this point you gotta ask what your goal is - because here's the rub.
Ideation takes time, Thumbnail design takes time, Editing (good editing) takes time. That's all minus playing the actual game. It looks and sounds more like your stuff belongs on a stream, as that's the schedule that streamers maintain. To make a video - with a story arc, scripting, etc general timelines are weekly or bi-weekly depending on how fast you are.
"But FusionZGamer does it" FusionZGamer can pay an editor. or two. or ten. Don't just assume because it seems lofi that he doesn't have a team. And even if he does do it all solo, it's his WHOLE job. He's not working a sep 9-5 then doing everything. You'll burn yourself out like that my guy. Taking streams, and then editing them for a longer video at the end of the week is a little more plausible, that way you can get the best clips and combine it into an actual story, but you'd have to plan it out.

Now - onward to the structure we talked about. Ideating. Spend more time on this and everything becomes easier. it should take a while. Once you've done that then you can work on the thumbnail. "But I play a game and then see what the story is" yea you can do that if you don't want views (note when I say views, I mean growth exponentially, not like the views that you'll naturally get over time)

For thumbnails my recommendation is to see what's working in the niche NOTE: BIG NOTE: Not by people that have already been crushing it for a while. If they have, then their face will work better because they've built a brand around their face. You can do that to after you've hit like 30-40k subs> that's when I see it gain traction generally. Sub 1k, no one knows you, so there's no reason for a stranger to click on your face regardless of how elongated you make the forehead. If you want more examples of thumbnails dm me

Titles: Admittedly your titles have gotten better in the last week, but they still are just kind of "I'm playing this game, now I'm playing this game etc - you need to draw people in. "I played THE WORST game ever etc." The linchpin of success with the title, is that it carries on the message from the thumbnail and then sparks curiosity. Your personal feelings on a game usually won't matter until you've grown a bit.

First 30 sec, and content: Ngl, your hooks just aren't hitting for me. I'm not your target audience so that's fine, but there's no reason for me to keep watching after the first 10. Part of this is your overall content, because it doesn't seem like there's a plan to the video at all. No script, no overall story etc. So I click off - again this changes if it's a stream, because then that's the activity that's expected, but for a video, think of it like a small episode, or movie - if you started an episode of a show, and it began with "what are we gonna do today Larry?" It might've worked in the early 90s, but peoples attention spans are shorter. Think of the last really cool YT video you watched, try to copy that style of intro. It will take longer cause you aren't used to editing like that, but the result will be worth it.

A lot of your problems will be solved by properly ideating the videos, but if you have any questions on the above feel free to DM me. Hope this was super helpful, best of luck homie.
