What I could suggest is for 4k game makers to test the UI on one or two persons before releasing. Stand next to them and tell them to try out the game, and then just watch them, note down what you see they’re having difficulty with. Also, tell them to describe to you what they’re doing while they’re doing it, what they’re thinking about doing and if they’re having problem with. Shouldn’t take more than 5-10 minutes to do this, and you’ll squash over 90% of usability issues. You can do this at school or work, or even home.
Btw. the bridge icon thingy wasn’t at all a big issue for me, beause even though it wasn’t easily understood I could deductively realize it was the bridge because no other icons were the bridge, and other icons were readable.
