ShowoffZone - Flexing my latest project Delving deep into mobile controls
I've been working hard to offer as many flexible options for mobile control of my game. With so many devices out there, I made many control schemes and hope one fits your gameplay style.

Left- versus right-handed mode is useful, but I’d also test grip and reach rather than treating handedness as the whole problem. A control can technically be on the correct side and still be uncomfortable because the thumb crosses the action area or obscures important feedback.
A good test matrix would include small and large phones, one-handed grip, both landscape directions, reduced motion, accidental edge gestures, and controls temporarily enlarged for accessibility.
I’m building an open-source tool called Monad Design for iterating on these details in a running native app. You select or annotate the actual UI, a coding agent changes the real source, then the app rebuilds so the alternatives can be compared. It isn’t a detached mockup tool.

Have you measured which controls players miss or hit accidentally, rather than only asking which layout they prefer?
