On Rusty Trails is a quick-reflex platformer built around a single idea: the world only tolerates things that look like it. Your character can switch form on the fly, and matching the right shape at the right moment decides whether a part of the level treats you as a friend or as a threat. Getting through a stage means changing your look constantly while running and jumping.
It is a single-player game from the small studio Black Pants, with short, demanding levels that reward practice and quick decisions. It suits platformer fans who enjoy trial and error, tight timing and a puzzle twist layered on top of the running and jumping.
