Why most mobile controls fail (and the few that don't)

The single biggest reason I bounce off a mobile game isn't the graphics or the story. It's controls that fight my thumbs. After hundreds of games, some patterns are obvious.

The worst offenders put important buttons in the top corners, where no thumb naturally reaches. Good games keep everything in the bottom third and make touch targets bigger than they look like they need to be. Fingers aren't precise.

Tilt controls are divisive, but done well — like in a solid arcade racer — they can feel more natural than buttons. The trick is a deadzone so tiny hand movements don't count. Games that skip that end up feeling twitchy.

Gestures are the wild card. Swipe-to-dash is great; swipe-to-open-a-menu-you-didn't-mean-to is not. My rule of thumb: if I trigger something by accident twice in the first ten minutes, the design's off.

The best control schemes are the ones you stop noticing. That's the whole goal.
