What others have to say


"Rusted Moss has elements of bullet hell, Metroid, Contra, and even Bionic Commando. It looks great, feels great to play, and swinging across gaps with my barrel blazing down on enemies felt incredible. It ticks an incredible number of boxes and, even in a short demo, made a long-lasting impression."

Ars Technica

"My PAX demo ended with a thrilling boss fight that forced me to shift my momentum as I hung on to a bungee-grapple point for dear life, dodging incoming projectiles while simultaneously adjusting my aim against a teleporting foe. If the full game can maintain that fresh, edge-of-your-seat feeling, it will be one to watch out for."

Rock Paper Shotgun

"Grapple hooks, shampple hooks. Everyone knows the best way to travel around Metroid-like universes is a grapple hook on a bungee cord. Yeah, that's right. Rusted Moss is a physics action platformer that knows how to travel in style, even if everything around you is trying to kill you all the time. Set in a beautiful, deadly post-apocalypse, machines, nature and the supernatural collide. This was one of the most intriguing demos we played at the whole PAX Rising booth. "
