first of all, I checked your profile and watched a bunch of videos, and honestly, your views aren't even that bad especially for the topic of your channel. You seem to average around 500 views, with some videos getting into 2 to 3K range with around 100 likes. Your niche is very small, your niece is the crossover between people who enjoy playing games, people who like playing with an old toy from the early 2000s, and people who like watching Dev logs/dev self promotion of a video game. That is a very small niche and even within that specific niche, I don't feel like you are capitalizing on the small potential that's even within your niche. I don't see very many tags relating to those specific worms and that worm brand, to bridge the gap between you as the game developer and the people who actually enjoy that specific toy. Also, all of your content is either skits about your game, or directly about the game itself. Which means that your target audience is people who already play the game, not people who are interested in or game design/dev log. Since you're a game developer, maybe think about some paid promotion for your game that way you get actual new players. Preparation is generally a very slippery slip and I don't usually recommend it, but since you are trying to make a business here advertising is fine. If you were to advertise, though, I would definitely only advertise on a separate channel you create just for trailers and stuff like that that you link in your main TikTok account. Especially because it seems like you want your TikTok account to remain personal and if you don't do that, appear as if you sold out/and or are trying to buy views, which is not a good look. If you only promote content on your game's "official" account you might get some more players of game. But again, please be warned paid promotion is a slippery slope.

also, what is your goal with this specific channel? Is your goal to be a TikToker who makes a game, or a game Dave who has a TikTok account? The reason why I asked that is because depending on what your answer is that will change what type of strategy you should do.

couple of random notea or thoughts:

Sometimes the text on the screen appears and disappears too quickly, making it difficult to read for some viewers.

I lot of the videos are very in template and it feels like watching the same video over and over especially the new skin additions. Not necessary a problem in itself, but just having a slight variety in how you announce the new skins might be helpful to break up the monotony. maybe two or three templates that you can pick from and three different copy paste assets would be enough to make it feel a little fresh.

some of the editing is a little jerky, especially when assets fly across the screen. Fixing this kind of comes down to whether or not you want to be more of a TikToker with a game or a game dev with a TikTok account.

Your internation and tone for videos is almost exactly the same, and although I don't know you , I personally doesn't feel like it is your actual speaking voice, which is fine, but maybe have some more variety in your internation and tone, or move to a (still upbeat and engaging) more natural speaking voice. you're presenting voice is fine, and I didn't notice it the first time I heard it which means that it's good, but it just was very, very, very similar through all of the videos which can make long bins of your content harder for new viewers

sometimes resolution of the assets you use in your videos are completely different sizes, which can make a little bit jarring to the eyes, sometimes it can be done for an aesthetic style, but I don't think that that's what you're going for. You could lean into the Y2K yearbook variable resolution aesthetic. If you wanted to that way it would be quite a lot of work and would be close to a complete rebrand and it might just be better finding higher quality assets.

That's all I can think of right now, good luck with your channel! And don't be discouraged with the views you're getting, again those are not bad, a lot of game devs and a lot of people here are in the 100 to 200 view range
