🎮 About the Game
Submeris invites you into an immersive underwater experience combining exploration, mining mechanics, and survival gameplay beneath a remote and mysterious island.
Start with just a simple shovel. Level up, upgrade your gear, and dive deeper into the unknown. But beware — limited oxygen, rising radiation, collapsing tunnels, and deadly sharks all stand between you and the ultimate treasure.
The deeper you go, the greater the reward — and the risk.

⚒️ Dig – Upgrade – Descend
Upgrade your shovel and pickaxe – dig faster and break stronger materials
Use dynamite and tools – break through obstacles and discover new paths
Use the detector – locate buried treasures and hidden cash beneath the ocean floor
Enhance your light source – illuminate dark tunnels below
Expand your inventory – carry more loot, earn more profit
Boost oxygen and radiation resistance – dive longer and go deeper

💰 High Risk, Greater Reward
In the depths, precious minerals, hidden chests, and legendary treasures await. But only the most prepared divers can survive the hazards below.
Radiation zones with time pressure
Unstable tunnels at risk of collapse
And most dangerously — sharks guarding the final treasure
Every layer hides danger, but also opportunity.
