Red and Green Rainbow

Grab a friend and split the screen in this color-coded co-op platformer where red and green have to leap, switch, and sync every move.

You've got two little blocks—one red, one green—on opposite ends of a hazard-filled screen, and the only way through is to move them both at once. That's the core trick of Red and Green Rainbow. One player handles WASD, the other takes the arrows, or you can both thumb it on a touchscreen if you're feeling brave. There's no combat here; it's pure platforming coordination. Double jump is your best friend, but it won't save sloppy timing. The levels are built so each color has to reach its own exit, often through separate paths that cross over and under each other. I remember a section where the green player had to stand on a button to lower a bridge for red—except red's bridge was over a spike pit and my friend kept pressing jump a half-second early. We died five times before we synced the countdown out loud. That's the kind of small frustration that turns into a victory dance. If you're playing solo, don't. This one really wants two brains. It's forgiving enough for a quick session but has enough tricky jumps to keep you from finishing on the first try. Red and Green Rainbow won't reinvent platformers, but it nails the couch co-op vibe.

*Move to WASD + Arrow Keys *Double Jump available *Mobile Touch Control

Master the double jump early—tap jump again at the peak for max height. Call out when you're about to press a button or trigger a platform. If one player dies, both respawn at checkpoint, so don't rush the other. Use the first few levels to learn each character's jump arc. On mobile, use thumbs on both sides; one finger per color.
