Game Feel: Make Combat Hit

Quest 6 of 11 in 2D Top-Down RPG.

Take a flat, lifeless sword hit and make it land. This quest is all about game feel: the disproportionate, layered feedback that separates a hobby project from a game that feels pro. You build one reusable Juice autoload, adding a single technique each lesson (hit flash, hit-stop, knockback, screen shake, floating damage numbers, impact particles, punchy SFX), then unify them into one Juice.hit() call that scales every effect to the weight of the blow. By the end the same swing you started with hits like a truck.
