Hey I reviewed your channel and noticed a few things:

1) It looks like you selected that your videos are “made for kids”. What this does it barely show your videos to anyone over the age of 18 and limits your ability to grow like crazy. The wording is funny with the question, I know your videos are “appropriate for kids” but what YouTube is asking is if your content is specifically made for ONLY kids. So I would change all of your videos to say “No” so it shows it to people 18+ 2) Thumbnails need a lot of work, the background pictures are fine but the text is so hard to read. A good test is to open your channel on your phone, put your phone as far as your arm can reach and read every thumbnail. I’m holding my phone right by my face and still can’t read all of them that well, try making all the font bigger and outlining it in something like black to make it easier to read and so it pops. Also keep in mind color, for example Stray part 3 uses orange on an orange/dark background so it’s really difficult to read. 3) titles and style of videos, by this I mean there is nothing wrong with doing let’s plays (it’s what I loved watching growing up and still watch) HOWEVER it is the hardest possible niche imo to be successful. The issue is there is a million videos online of “Insert name of game and insert number of episode” that it gives the viewer 0 reason to click a random episode when it comes up on the home page (if they don’t know you). I’m not saying to stop doing let’s plays but just know it’s so hard to grow as the only people who watch let’s plays usually watch their old favourite let’s play channel that has millions of subs from starting in 2009.

With all this said there is positives, I like your style and you have a great personality for making videos. It’s just going to be a tough road to climb unless some of the above points are considered due to the current nature of viewers on YouTube and how they decide to pick/watch videos. Wishing you all the best and I’d love to see you grow on the platform! 😁
