I have no idea how youtube gets it's recommendations when this happens, but if it's some sort of randomish fallback list, I can easily believe that cheap, mass produced kids content is a huge fraction of youtube uploads/views.
So I took a closer look at it and I think the gray is too bright and the font itself... Well, it isn't too bad, but I wouldn't consider it elegant nor readable.
Apart from the font, I like the clean look and minimal layout.
I hope this feedback helps to improve the theme for future versions ;-)
Otherwise I think it looks great though, nice job!
Especially interesting is seeing how the times and what we expect from videogames have changed, on page 23 there's a dejected nod to people expecting a 90s first person game to have multiplayer, even though it's primarily a single player RPG, but they'll do it as a bullet point to go on the back of the box.
The only mobile games I can bring myself to recommend are Andoku Sudoku, The little crane that could, and crossy road (which even includes monetisation schemes without feeling intensely annoying).
Suggestions for others would be appreciated
