# Change Notes

####   
01/24/2019

Game concept and pitch were created: This game was originally pitched as a project for the LWTech GAME BAS 2020 Cohort’s 2D Game Design class. The idea is to have a game that our team of 14 students can produce in about 5 weeks. The idea isn’t particularly complicated or unique, but should be achievable in the allotted time.

#### 02/13/2019

Game ideas were pitched to the class, Chucky & Dexter received the majority vote to be the game we work on for the rest of the quarter.  
Began converting the game pitch document from concept material into proper Game Design Document that can be used for development.

#### 02/14/2019

All major areas of the GDD were completed, document was shared with team and opened for comments.

#### 02/20/2019

Fixed a hand full of typos. Clarified some small areas. Improved list of milestones. Added a Sound Design section. Added art director’s style guide to Art Design section. All comments from this week up to this point have been resolved.

#### 02/21/2019

Updated list of sound effects

#### 02/27/2019

Added art director’s color notes to the Art Direction section. Added the list from “Needed Assets For Title Screen.docx” into the GDD under a new “User Interface, Title Screen, and Menu” section.

# High Concept

**Chucky & Dexter** is a casual two player local co-op puzzle-platformer game. An alternative to violent action-heavy games, it is packed with cute characters, and a light-hearted atmosphere. The game is intended for couch co-op; controls are designed for two Xbox controllers (one for each player), and the visuals and level designs will be large enough to be seen from the couch.

The levels have to be navigated as a team. The core gameplay is platforming similar to [BattleBlock Theater](https://www.youtube.com/watch?v=pv1ZoHt6poI). What makes this game different is that the co-op is asymmetrical; both characters have a set of abilities and limitations that compliment one another.

Player One plays as **Chucky**, a baby elephant who is slow and heavy, can move large obstacles, and can vacuum up objects with his trunk, then chuck them across the level (this includes your co-op partner)

Player Two plays as **Dexter**, a monkey who is small agile, and dexterous. He can interact with small buttons / control panels, can climb ladders and monkey bars. And can be thrown by Chucky to gain access to far areas of the level.

Together, Chucky and Dexter have to escape the circus while solving small puzzles to get to each new area, and avoiding obstacles, and animal control officers. For our demo we can build 3-5 levels. Each level must be exited by both Chucky *AND* Dexter via the exit door. The game is over when you complete all of the levels.

# Art Direction

Naming convention: **EnvironmentTiles\_128x128.png**

Art is high-fidelity (AKA not pixel art) sRGB

Environment tiles are 1x1 Unity unit, and 128x128 pixels each.

Art submissions are to be submitted as **.png** (If Photoshop’s way of handling .png alpha channels causes problems there is an exporter plugin that we can use to fix it.)

For characters, don’t cramp your assets into the 128x128 space, give them room to breath, otherwise natural looking character movements are difficult to achieve.

[![image23.png](https://docs.bugjam.dev/uploads/images/gallery/2025-12/scaled-1680-/image23.png)](https://docs.bugjam.dev/uploads/images/gallery/2025-12/image23.png)

Test out the size of the assets in the scene (especially compared to other similar assets) before detailing and or animating.

Art should be drawn at a slight angle, the doorways and characters will look extremely awkward if they are drawn exactly from the side angle

##### Common Controls:

- Menu - **Start Button**
    - Restart Level
    - Level Select
    - Quit Game
- Walk - **Left Thumb Stick**
- Swap Characters - **Back Button** (primarily for being able to test the build solo)

##### Chucky Controls:

- Kick - **A Button**
- Suck up object with trunk - **Hold B Button** (while not currently holding an object)
- Aim Trunk - **Left Thumb Stick** (while holding B Button)
- Chuck Object - **Release B Button** (while holding Left Thumb Stick to aim)

##### Dexter Controls:

- Jump - **A Button**
- Interact (press button, pick up key, use key, shake coconut from tree) - **B Button**
- Climb Ladders / Monkey Bars - **Left Thumb Stick**

Co-Op Camera (keeps both characters framed on screen)

# User Interface, Title Screen, and Menu

Neutral state: The object/menu option is not being hovered over.  
Active state: The object/menu option is highlighted (being hovered over but not pressed).  
Pressed state: The object/menu option is clicked on (or player presses A while it is highlighted) The active state must be noticeably different from the neutral states.

All Button Assets must be consistent to the size of the largest file! I.e. If your button gets bigger when in the active state, you must save the neutral and pressed state image .pngs so that they have the same pixel dimensions as your active state.

The buttons can look however you and the art director decide, as long as there is one for each state and the states are consistent. I.e neutral states must all be the same color, active states must all be the same color, etc….

### Title Screen

##### Menu Assets

- Game Logo
- Title Screen Background
- “A To Select” image

##### Buttons

- Play (Neutral state, Active state, and Pressed state)
- Level Select (Neutral state, Active state, and Pressed state)
- Options (Neutral state, Active state, and Pressed state)
- Exit Game (Neutral state, Active state, and Pressed state)

### Level Select Screen

Level slot refers to an image of the level with some identifier for which one it is. I.e, screenshot of level one with “Level 1” in text below it.

The active state must be noticeably different from the other states

Level assets must consist of levels 1 - 5 and include assets for one named “Tutorial”  
Creating fun names that match the theme of each level is acceptable as well, talk to the level designer about that.

Level Screenshots and/or animated gifs (Communicate with Level Designer whenever that is decided)

##### Menu Assets

- “Level Select” text
- Level Slot Background
- “B To Return” image

##### Buttons

- Level Slot (Neutral state, Active state, and Pressed state)

### Options Screen

##### Menu Assets

- “Options” Text
- Background panel to see options clearly
- Custom art for a volume slider
- “Volume” text
- “B To Return” image

# Level Design

Levels are to be built as individual scenes  
“Game Handler” types of objects can be set to persist between level loads.

When designing levels consider the number of actions Chunky gets to perform vs the number of actions Dexter gets to perform. They should be as close to equal as possible. Don’t have Dexter doing everything while Chucky sits idle.

##### Level 1

- Essentially a tutorial level with few puzzle elements

##### Level 2

- introduce a few more puzzle elements

##### Level 3

- Introduce Animal Control Officer

##### Level 4

- Interesting puzzle design using many elements

##### Level 5

- Final challenge using as many puzzle elements as possible
