How to grow my content! I need help.

So I'm a small YouTuber with about 208 subscribers and I just do the platform for fun, but want to reach at least 1000+ subs. How can I do it? For a while I did Roblox content, playing games like Piggy and Bedwars, but I grew out of Roblox a bit, and aren't as interested. Today, my capture card that I ordered arrived, and I posted a video of myself playing Hollow Knight on my switch 2, and it didn't do as well as I thought. I also haven't uploaded for 7 months, which doesn't help. Any advice?
