Rat Climber is a deceptively simple yet deeply engaging 3D "ratformer" that puts you in the paws of Ratty, a determined little rodent on a single-minded quest to reach the top and claim the ultimate prize: cheese. There are no convoluted upgrade trees, no hoards of collectibles you’ll never use, and no hidden power-up systems. Instead, you’re given just three basic actions-walk, jump, and dash-and asked to think like a rat as you scramble up a series of vertical labyrinths.
