Goal: Prove that throwing geese at enemies in a first-person tower defense arena is fun.

Core Systems to Build:

1. First-Person Player Controller

Create using Godot's CharacterBody3D with:

Mouse look, WASD movement, ground snapping/gravity
Optional head bob, sprint
Throw input triggers projectile creation

Structure:
Player -> Camera3D + ThrowOrigin (Marker3D at hand)

2. Goose Projectile

Use Area3D or RigidBody3D with:

MeshInstance3D, CollisionShape3D, AnimationPlayer
Behavior: spawn from ThrowOrigin, apply velocity based on camera direction, apply spin
On hit: damage enemy, play honk, spawn hit effect, queue free

3. Enemy

Start with one enemy type:

Structure: Area3D/CharacterBody3D with Health component
Behavior: spawn at point, move toward base/player, attack when close, take damage, die and drop currency
Simple movement: direction := (target - global_position).normalized(), velocity = direction * speed, move_and_slide()

4. Basic Wave Spawner

Wave manager behavior:

Start wave, spawn enemies over time, track remaining enemies
When all dead, start next wave; after final wave, player wins
Data structure using Resource for WaveDef with enemies, spawn_interval, reward

5. Basic Economy

Enemy dies -> player gains feathers (100 starting, 5 per enemy)
Player can buy additional goose throws or better goose
Every 10 enemies, unlock extra goose in reserve

6. Minimal UI

Top-left: health, currency
Top-right: wave number, enemies remaining
Center: crosshair
Menu: resume, restart, quit

7. Win/Lose State

Win: survive all prototype waves
Lose: player health reaches 0 or base health reaches 0

Prototype Deliverables:
Single playable scene with first-person movement, mouse look, throw geese that hit enemies, enemies move/take damage/die, currency increases, waves progress, clear win/lose state.

Exit Criteria:

Core loop is playable
Throwing geese feels responsive
Enemies can be killed
Waves work
Economy works minimally
Game has clear win/lose state
