It’s an interesting concept, and quite fun to play as well.
My main complaint is the bugs. Not sure if it’s browser-related or not but the tutorials were partially out of screen (which got somewhat fixes by lowering the page scale and reloading the game), and dragging the camera was kinda weird. I lost because of that - it took me too long to find where the computers are.
I’d also suggest increasing the hitboxes for computers and links - these were on the smaller side making it harder to click, especially since this is a thing you want to do quickly.
As for the gameplay, I didn’t feel a need to switch the flow on half-duplex links. Maybe you could add an indicator near the computers that would slowly fill up if they don’t send data for a while? That would allow me to see when it’s time to switch these.
Good job on your entry, I think with a bit of polish and bug fixing it’ll be a great little game!
