WASD: Move forward, backward, left, and right.

Gameplay:
When the protagonist steps on an icon, a gauge will fill up. Once the gauge is full, an item will appear. Use these items to craft and create new items.

Weapons:
The simplest weapon to craft is a sword. A sword can be crafted using "stone" and "wooden stick."

Crafting:
When the player steps on the icon with a crossed hammer and wrench, a crafting interface will appear. Place items in the designated slots and press the hammer button to start crafting. If the required items are present, the crafting will succeed, and an item will be created. If unnecessary items are present, the crafting will fail.

Shopping:
There are three shops on the map. When the player steps on a shop icon, the shop menu will open. In these three shops, you can purchase "animals," "stages," and "allies."

Animals: Chickens produce eggs, which can serve as an early source of income.
Save money to purchase stages.
Allies: There are four types of allies—soldier, nurse, robot, and thief.
- The soldier shoots enemies with a gun.
- The nurse heals the player's health.
- The robot restores the durability of cards.
- The thief periodically drops money.

Enemies:
Zombies can throw cards or deal damage by touching the protagonist. Craft weapons to defeat them.

Objective:
The ultimate goal is to craft a ship and escape the island. You can craft a ship using the necessary items, "sail" + "turbine." This is the goal of the game.

Others:
In the bottom left corner of the screen, there are two icons.
