“The Coma 2: Vicious Sisters” is a 2D survival horror adventure game developed by the Korean independent game team Devespresso Games. This installment continues the tense atmosphere of its predecessor, with players taking on the role of high school student Mina, who must evade the blade-wielding vicious pursuer “Ms. Song” in the cursed Sehwa High School and its surrounding areas late at night, and explore dark secrets in order to survive. This guide will provide a detailed breakdown of the core interface, complete operation flow, and advanced tips for the Mac version of the game.

I. Core Interface and Workspace Breakdown

The game uses a 2D side-scrolling perspective, with a clean interface design that delivers information clearly, mainly divided into the following areas:

Main Game Area (Center Area): Displays the game scene, characters, enemies, and interactable objects. The visual style is hand-drawn dark comic art, and lighting and shadow effects are key clues for evading enemies.
Character Status Bar (Top Left Corner):
- Health (Heart Icon): Represented by the number of hearts; taking damage reduces them, and when they reach zero, the game ends.
- Stamina Bar (Green Bar): Located below the health value; it depletes rapidly when sprinting, and once exhausted, you can only walk.
- Item Quick Bar (bottom-left): Displays currently selected usable items (such as bandages and energy drinks).
Map & Objective Indicators (top-right):
- Press the M key to open the full-screen map. The map displays explored areas in real time, important locations (such as save points and shops), and the current main quest objective locations.
- Unexplored areas appear as black shadows.
Interaction Prompts (bottom-center of the screen): When the character approaches an investigable object, door, or NPC, a text prompt will appear (such as “Investigate” or “Talk”), along with the required key press (default: E key).
Menu Interface (press ESC to bring up): Includes “Inventory,” “Map,” “Journal,” “Settings,” and “Return to Title Screen” options. The inventory is used to manage consumables, key items, and notes.

Interface Tip: In-game lighting is extremely dark. It is recommended to appropriately increase brightness in system settings or in-game to better observe environmental details and enemy silhouettes.

II. Complete Operation Walkthrough: From Launch to Completion

The following walkthrough covers the core operation steps from starting the game to completing a typical chapter.

Step 1: Create/Start a New Game

After launching the game, on the main menu screen use the arrow keys (↑↓) or mouse to select “New Game“, then press the Return key (Return) or left mouse button to confirm. The game offers multiple save slots; select an empty slot to begin.

Step 2: Basic Movement and Environmental Interaction

Movement: Use the A key (move left) and D key (move right) to control the character’s horizontal movement.
Crouch/Dodge: Press the S key to make the character crouch, which allows you to enter low-clearance spaces and also dodge enemy sight lines behind cover.
Sprint: Hold the Shift key while moving to sprint, which rapidly consumes the stamina bar.
Interact: Walk up to an interactable object and press the E key to investigate, pick up, or open doors.
Use Items: Press the Tab key to open the inventory, use the arrow keys or mouse to select an item, then press the E key to use it. After assigning commonly used items (such as bandages) to the quick bar, you can press the number keys 1-4 to use them quickly.

Step 3: Core Survival and Evasion Mechanics

Evading Teacher Song: When you hear tense music or footsteps, it means the enemy is approaching. Immediately hide in a wardrobe, under a desk, or in a compartment (press the E key when nearby). Stay quiet while hiding until your heartbeat returns to normal.
Saving the Game: Find the red telephone booth in the scene, approach it, and press the E key to save your progress. This is the only way to save, so please save often.
Restoring Health and Stamina: Use “bandages” to restore health; “energy drinks” can instantly restore some stamina. Items can be obtained from vending machines (using the in-game currency “won”) or from specific NPCs.

Step 4: Puzzle Solving and Mission Progression

Check Missions: Press the J key at any time to open the journal and view details of your current main and side missions.
Map Navigation: Press the M key to open the map; yellow exclamation marks indicate the locations of current mission objectives. Plan safe routes and avoid enemy patrol areas.
Puzzle Elements: Most puzzles require you to find key items (such as keys or password cards) or piece together information (such as obtaining a code from notes). Search every room carefully and don’t miss any glinting spots or interactable objects.

Step 5: Final Export (Completing the Game and Chapters)

The game has no traditional “export” feature. After completing the final story sequence, the credits will play and you will return to the main menu. Your completed save file will be marked with a special indicator. To experience different endings, you need to make different choices at key decision points (such as whether to save a certain character) and replay the subsequent chapters.

III. Advanced Tips for Common Features

Efficient Stamina Management: Don’t sprint the entire time. Walk in safe areas to recover stamina. When encountering enemies, short, rhythmic bursts of sprinting by tapping Shift are more efficient than continuous running.
Sound Detection: Headphones are recommended. The direction and intensity of enemy footsteps allow you to pinpoint their location accurately. Ambient sound effects (such as announcements or background noise) can sometimes indicate danger or hidden items.
Map memorization: After opening the map (M key), memorize the enemies’ usual patrol routes (such as corridors and halls), and use zigzag paths to avoid them. Unexplored black areas may contain supplies, but they are also high-risk.
Quick inventory management: In the inventory, place commonly used healing items on the same row so you can quickly select them with the arrow keys in emergencies. Unnecessary note-type items can be ignored and take up no space.
Luring and diversion: In some scenes, you can deliberately make noise (such as running past breakable objects) to lure enemies to a specific area, then quickly detour to your destination.

IV. Common Problems and Solutions

Symptom	Possible Cause	Solution
The game crashes on startup or won’t open	Incompatible macOS version or permission issues	1. Confirm that the system is macOS 10.13 or later. 2. In “System Settings” > “Privacy & Security”, check whether the app is allowed to run. 3. Try right-clicking the application icon and selecting “Show Package Contents” to run the executable file directly.
Severe stuttering or frame drops during gameplay	Insufficient Mac graphics performance or background processes consuming resources	1. In the in-game settings, set visual effects and shadow quality to “Low”. 2. Close all other applications, especially browsers and video software. 3. Make sure the Mac is in charging mode for best performance.
No response or delay in key operations	Keyboard input conflict or in-game key settings reset	1. Go to the game’s “Settings” > “Controls”, check and reassign the keys. 2. Disconnect possible external devices (such as other keyboards or game controllers) and test. 3. Restart the game.
Unable to save the game (no response from the phone booth)	The game’s story has not been triggered or the save point is temporarily disabled	1. Advance the main story until the game explicitly indicates that saving is available. 2. Make sure no enemies are chasing nearby. 3. Try interacting with the phone booth from a different angle.
Game progress lost	Abnormal exit or corrupted save file	1. Always save through the in-game phone booth, and use the menu’s “Exit” function rather than force-quitting the app. 2. Check whether there is a backup in the save file folder (the game-related folder under ~/Library/Application Support/). Games usually have multiple automatic backup saves.
