About the game
You need to go up... but you cannot jump! Mount Lomyst is a 2D platformer where you must reach the summit using only a grappling hook and your climbing skills.
Original Steam description
Return to the mountain where Grandma disappeared.
A 2D platformer with no jumping.
Mount Lomyst is a 2D mountain-climbing action platformer where you climb a snowy peak using only a grappling hook and climing walls.
No-Jump Action
The only tools are a hookshot and wall climbing.
Observe the terrain, choose your route, and make your way upward.
One mistake can send you sliding far back down, so climb carefully.
One Vast, Connected Mountain
Experience the climb as one seamless journey, continuing ever higher up the massive Mount Lomyst.
Face environmental challenges that change the way you climb, including strong winds, crumbling footholds, and walls your hookshot cannot latch onto.
With no enemies and no NPCs, this is a quiet climbing experience where you face only the mountain itself.
Features
A linear 2–3 hour gameplay experience
Fully handcrafted levels
Simple, stylized visuals
A quiet story told through notes left behind
