Tallman Run is an arcade runner where you grow taller and wider to smash obstacles and reach the finish in style.
Swipe left and right to line up with growth gates that add height or width. Run through boosters to get bigger and avoid traps that shrink you. Break barriers only when your size is high enough. Reach the final platform and outsize the boss to clear the level. Collect gems to unlock new skins as you progress.
Tip Aim for the gates that boost the stat you need next so you can break the biggest barrier on your path.
