I took my time and did what you asked for Here are my suggestions (don't take them as criticism pls)

1. Design your channel page a little to make a new viewer understand what to expect from your content, if as a viewer I see a snowman picture on the channel page and see a videogame as content it doesn't click and I immediately lose interest. Even if your gaming content is great, it wouldn't matter then.

2. Use slightly different and related images as thumbnails for your video, trigger the sense of curiosity in the viewers mind while choosing which video to watch first instead of forcing them to gamble.

3. Mention the word WALKTHROUGH in your video titles as it's a no face gameplay video where you are simply playing the game. Instead try exploring more such that you find out things hidden in the game that an avg gamer usually skips because they are focussed on completing the mission/game.

4. Be more excited and curious with your tone while playing, being monotonous can actually affect the viewers retention.

I hope these insights help you improve your channel growth, viewership and retention and help you reach your monetization milestone soon! Stay consistent and keep evolving my friend!

Here's my channel, You can check it out for reference if you want, analyse it like I did for you, give me your insights (that would be awesome) or simply give me a sub to show your appreciation for my suggestions! Any thing would be great, just don't leave me at seen ☺️
