# YeetGeese - Design Document
|
||
|
||
## Game Concept
|
||
**YeetGeese** is an over-the-shoulder third-person tower defense game where the player defends a base by throwing geese as powerful projectiles. The core fantasy is absurdly simple but deeply satisfying: enemies approach your objective, and you yeet geese at them to stop them.
|
||

|
||
|
||
## Core Fantasy
|
||
> *"I am alone in a 3D farm arena, viewed from behind my shoulders. Farm animals march toward my base. I aim with mouse, throw with a click, and watch geese crash into foes with satisfying honks, spins, and impact. Each throw feels powerful and purposeful."*
|
||
|
||
- **Player**: A lone defender in over-the-shoulder third-person
|
||
- **Weapon**: Throwable geese that act as both projectiles and temporary turrets
|
||
- **Objective**: Protect the base from waves of approaching farm animals (Pigs, Chickens)
|
||
- **Juice**: Every goose hit produces satisfying feedback (honks, feathers, screen shake)
|
||
|

|
||
|
||
## Core Loop
|
||
```
|
||
[ENEMIES SPAWN] → [PLAYER MOVES & AIMS] → [YEET GEESE] →
|
||
[GEESE DAMAGE/DISTRACT ENEMIES] → [CURRENCY COLLECTED] →
|
||
[BUY UPGRADES/NEW GEESE] → [WAVE COMPLETE?] → [NEXT WAVE (HARDER)]
|
||
```
|
||
|
||
### Breakdown:
|
||
1. **Enemies spawn** at designated points and march toward the base
|
||
2. **Player moves** through the arena in third-person, positioning for optimal throws
|
||
3. **Player aims and yeets geese** using mouse look and click
|
||
4. **Geese impact enemies**, dealing damage or causing knockback/stun
|
||
5. **Currency drops** (feathers) from defeated enemies
|
||
6. **Player spends currency** on upgrades or new goose types
|
||
7. **Wave ends** when all enemies are eliminated
|
||
8. **Next wave begins**, with more/enemy variety/difficulty
|
||

## MVP Scope
|
||
|
||
### One Arena
|
||
- Simple, open arena with clear spawn and base zones
|
||
- Neutral terrain allowing free movement
|
||
|
||
### One Player Controller
|
||
- **Player Controller**: Over-the-shoulder third-person view (WASD + mouse look, throw input)
|
||
- **Basic health system**
|
||
|
||
### One Goose Type
|
||
- **Basic Goose**: Standard projectile goose
|
||
- Medium damage, standard speed
|
||
- Spins on throw
|
||
- Flees after impact or short lifetime
|
||
|
||
### Two Enemy Types
|
||
1. **Pig** (formerly Grunt) – Slow, low health, standard damage (meat shield)
|
||
2. **Chicken** (formerly Runner) – Fast, low health, reaches base quickly
|
||
|
||
### Five Waves
|
||
| Wave | Enemies | Description |
|
||
|------|-----------------------------------|---------------------------------|
|
||
| 1 | 3 Pigs | Tutorial wave |
|
||
| 2 | 5 Pigs | Slight increase |
|
||
| 3 | 4 Pigs + 2 Chickens | Introduction of speed |
|
||
| 4 | 6 Mixed (Pig/Chicken) | Mix of both types |
|
||
| 5 | Boss wave: Oinker Boss | Large, high-health farm animal |
|
||
|
||
### Basic Economy
|
||
- **Starting currency**: 100 feathers
|
||
- **Enemy drop**: 5–10 feathers per kill
|
||
- **Goose cost**: Free for first type
|
||
- **Upgrade/shop unlock**: Every 10 kills unlocks new goose slot
|
||
|
||
### Basic UI
|
||
- Top-left: Health bar, feather count
|
||
- Top-right: Wave number
|
||
- Pause menu (Escape)
|
||
- Game over / Victory screens
|
||
|
||
### Win/Lose Conditions
|
||
- **Win**: Survive all 5 waves
|
||
- **Lose**: Player health reaches 0
