I think the game's theme could still be better implemented on the page. Adding the coins, balls, bricks and powerups to make your page look more lively - unless you're going for a super plain look which is fine, but even then I think a plain background could still be designed better. Also noticed the background image seems blurry, so might need to upscale a bit.
The content page itself could also be better designed I think, you can add dividers and split it up into categories with PNG pictures of "About" "Controls" in the style of your game's font style. I also think GIFs inside Projects whether in the banner, cover page, or content is always a +1 to a project's design.
