On small-enough screens (I use Snap! on a mobile device often), the top bar has no links, except for a button with no text or symbol to the right, which reveals the top bar options, in rows. This is honestly bizarre for me. Likely due to the Bootstrap framework.
If you want to see it, go ahead and use developer tools to emulate mobile. I believe shrinking the window size will too trigger that.
There is a menu button (which looks like there should be a symbol, but there isn't) that when tapped, shows all the missing links.
I think the OP already knows.
Oh yeah. Well, even then, I don't see any issue with this (besides the button having nothing on it), because trying to show them the way they are on desktop, would be terrible. Just look at project pages (they still haven't gotten the update).
Okay. This is fine for very small screens, but the language option needs to take up more of its row rather that just showing an icon. But, I lower the page zoom so the page looks smaller, and the UI looks somewhat quirky having it like this. They could have made some of the options show up and hide the rest of them in the menu.
I feel like just "Run Snap!" Should be out of the menu if it can fit, because I feel like that's the most important link.
There's an issue with the coloring on the button. It will get fixed at some point.
The nested menus are a problem. 
both for user actions and and languages...that will take more work to design an actually better interface, but in most cases there's going to be scrolling.
'Run Snap!' really can't be shown the entire time by default because on many screens when both the logo and the button are shown there isn't enough room -- and on a screen that narrow, I don't think you really want to open Snap! all that often anyway..
