This is a small nitpick, but something that is a bit frustrating to find out the first time.  Currently on the itch.io app, when looking at a game page, the page's background has a different width than the website when viewed through something such as chrome. This makes backgrounds that repeat and work on something such as the itch app, not work on the chrome equivelent. 

I'm not sure exactly what can be done to get around this, it seems the extra space is entirely taken up by the left Explore/Library/Collections/My Creations tab on the left. 

Potentially I made an error miss-sizing my background but I imagine I'm not the only one with this issue. Visual consistency should be aimed for regardless.  Luckily for me this is a simple fix (I'm just going to change the one color mismatched tile).

Thanks for making itch awesome!
