I checked out a few of your videos.
They are entertaining(I liked the Happy Wheels video). But there are so many channels like yours on Youtube, that it won't be easy to get noticed. There's a saturation of gaming channels on YT.
My advice to to network your channel through forums with similar content, make collaboration videos with other gamers, and comment on other gaming channels. If they notice you post comments on there, they will check out your stuff.
