Quick answer: Define an explicit focus order that follows the visual reading order (top to bottom, left to right), and set neighbor links for every navigable control.
Focus that leaps from the top button to a corner toggle disorients keyboard and screen-reader users. An explicit order fixes it. Here is how.
How to fix it
1. Map the intended order
Decide the logical sequence a sighted player would read the screen, then assign that order explicitly instead of relying on instantiation order.
2. Set directional neighbors
For grid and list menus, wire up-down-left-right neighbors on each control so D-pad navigation moves predictably and never lands on nothing.
3. Trap focus in modals
When a dialog opens, move focus into it and keep focus contained until it closes, then restore focus to the control that opened it.
Catching the ones you can't reproduce
The hardest version of this to fix is the one you can't reproduce — it only happens on a player's hardware, OS, driver, or save state, under conditions that simply aren't present on your machine. A report that says “it crashed” or “it froze” gives you nothing to act on, so the bug survives release after release while quietly costing you players.
Automatic error capture closes that gap. Each failure arrives with its full stack trace, the device and OS, the build number, and a breadcrumb trail of what the player did right before it broke, so even a failure you have never seen becomes a specific, reproducible issue. Fold identical failures into one signature ranked by how many players each hits, and your worklist sorts itself worst-first instead of arriving as a stream of vague complaints.
This is where a tool like Bugnet earns its place. Its SDK captures every error automatically with the full stack trace plus device, OS, memory, build, and game-state context, folds duplicates into one grouped issue with an occurrence count, and ties each to the build it first appeared on — so you fix the problem that hurts the most players first and confirm it is gone when its signature disappears from the next release.
A crash you can name from its stack trace is a crash you can usually fix in minutes.
