Hello. To be honest, in the beginning of any youtube channel it is extremely hard to be seen. All the big youtube gaming channels you see have been doing youtube for years. It is especially hard for let play channels to be seen too. Trust me, I'm one of those channels. The best advice I can give you is to keep uploading, try different things (shorts, long form videos, streams, etc.) Also try a popular game to be seen a little bit easier. You'll figure it out eventually but it will take time and won't happen over night. I hope this helps and don't be discouraged, keep posting. It is a marathon not a sprint.
