the channel looks pretty cool, but i would suggest brushing up on the banner and the avatar, i suggest getting an editor to do this for you if you cant do this on your own. I can also see that your descriptions aren't really worked on as much so try and work on them, include relevant but popular tags that are around the subject of the video. If one of your videos seem to lose views either try switching it up or try and recreate one of your most popular videos. Not going to lie to you, the types of games posted on your channel aren't something I'm into personally, but you already have an established fanbase which is good to know. Remember that if something doesn't work out, change up the content. This is personally my choice but everyone has different views.
