This is a casual first-person shooter game. You don't need to walk—just move your mouse to aim and shoot at targets.

On the sea at night, many unlit lantern signs have appeared. You can shoot at these signs to charge them with energy. When the energy reaches the right amount, the sign will be successfully lit up, and you will earn points.

However, each shot you fire increases the energy level of your gun by a small amount. If a single shot's energy exceeds the amount required by the lantern sign, the sign will be damaged.

So, constantly changing your target to match your gun's current energy level is a viable strategy.

(Each time you light up a sign, your gun's energy resets to its initial state—after all, we can't let it grow indefinitely, right?)

The game includes at least 30 challenge levels, which will also help you understand the core gameplay. After completing the challenge levels, the game will unlock Endless Mode, a gameplay loop where you can keep trying to achieve the highest score.
