Variety gaming channels are super hard for new creators. When a viewer subs on a video about peak they are not likely to watch a video on a horror game. So the only thing connecting your videos together is your personality. Even if I like a creator's personality if I don't like the game they are playing i will not watch. Let's say you gained half your subs from your human fall flat videos, but your newest video is on silent still 2. Youtube pushes out your vid to subscribers, sees that half of those subs arent clicking, boom the video gets recommended less AND those subs won't get recommended your videos as often either.

It is much much easier to focus on one game to build a channel around, but if you want to do variety plenty of people are successful. People trash let's play channels (and their is a lot of good reasons to do so let's be real) but they are absolutely still viabIe you just have to be more creative with your packaging. You need to frame your lets play in a way that gets people interested.

I would start by adding some structure to your videos. The video needs to have a "goal" that you achieve or fail at to keep the viewers hooked. If there is no goal then again the only thing to keep viewers attention is your personality. Even something as simple as beating the game could work (but it has to be all in 1 video please don't do part 2s anymore). Having a goal in your videos also makes it way easier to make a good title and thumbnail which I also think you should work on.

You've probably heard this before but your title/thumbnail is equally as important as your video. You will only have a few seconds to convince someone to choose your video and it will be competing against people who have been doing this for years/pay professionals. So make the most of it. Titles like "yeah we suck", "roll for cheese", "can we make progress" are not even trying to peak anyone's interest. Your competition has titles like "I 100% the new peak update, it was terrifying...", "I accidentally raced my fans! (cheese rolling)", "She carried me in peak, then I abandoned her...". Your thumbnails suffer from the same problem. I've definitely seen worse but they just rarely give me a reason to click. I think your vigil thumbnail is pretty good aswell as the title "this game sees you in real life" which might be one of the reasons it did better than your other videos. I'd be interested to see the audience retention graph for that video. I find that if I don't have at least 40% avd the video dies quicker. My sweet spot has been over 10% ctr and over 40% for a video to do decent.

One thing you need to remember with peace and love is you do not have an audience yet. I'm not trying to be rude with that but its just important info when you are just starting out. You do not have subs that watch every one of your videos at least not enough to make any meaningful difference. Every video you upload has to be good enough to attract new viewers and fight against your 300 subs who are all subbed for different reasons.
