RedRunner is a fast-paced 2D side-scrolling platformer where you guide a red character through increasingly difficult levels packed with traps, enemies, and hidden secrets. Your main tools are running, jumping, and rolling - and knowing exactly when to use each one is what separates a clean run from a messy death. The controls are tight and responsive, which means every mistake is on you, not the game.

Each level throws new obstacles at you, from precision jump sequences to enemies that require quick decision-making on whether to dodge or power through. Rolling is surprisingly useful for slipping under low barriers and avoiding certain attacks, so don't sleep on it. The fast-paced action means you're always moving, always reacting, and stages are short enough that restarting after a death never feels like a punishment - it just pushes you to do better.

RedRunner is a great pick for fans of classic 2D platform games, retro-style side-scrollers, and anyone who enjoys skill-based challenges that reward practice. If you like free online platformer games with tight controls, old-school adventure gameplay, or browser-based action games you can jump into without downloading anything, this one delivers exactly that. It's a solid choice for quick sessions or longer grinding runs when you're chasing a clean playthrough.
