I played Free Fire with two thumbs for a long time and thought I was “bad at aiming.” The real issue was math: three actions, two fingers.
The two-thumb trap
Left thumb moves. Right thumb aims. When you need to fire, the aim thumb leaves the screen — aim freezes — you stand still — you die.
It’s a finger-count problem, not a talent problem.
What claw does
A third (or fourth) finger stays on fire. Aim never has to stop. Expect it to feel wrong for a few days. That awkward phase is normal.
Before you buy hardware
Try claw before a clip-on gamepad. If aiming-while-moving is still the blocker after claw feels natural, then a gamepad is a fair next step.
