1. Core Loop Design

The 30-Second Test

Every game needs a fun 30-second loop:
1. ACTION → Player does something
2. FEEDBACK → Game responds
3. REWARD → Player feels good
4. REPEAT

Loop Examples

| Genre | Core Loop | |-------|-----------| | Platformer | Run → Jump → Land → Collect | | Shooter | Aim → Shoot → Kill → Loot | | Puzzle | Observe → Think → Solve → Advance | | RPG | Explore → Fight → Level → Gear |

Essential Sections

| Section | Content | |---------|---------| | Pitch | One-sentence description | | Core Loop | 30-second gameplay | | Mechanics | How systems work | | Progression | How player advances | | Art Style | Visual direction | | Audio | Sound direction |

Principles
