# [Game Name]: Game Design Document
*One-page friendly. Fill in what you know, delete what you don't need. Keep it short and update it as you build.*
## 1. The pitch (one sentence)
> "[Game name] is a [genre] where you [main action] to [goal]."
Example: "Blaster Belt is a puzzle game where you send blasters around a conveyor to pop pixels and reveal a picture."
## 2. Who is it for?
- **Players:** (age, what they already play)
- **Platform:** Roblox / PC / mobile / console
- **Session length:** how long is one play session? (5 min? 30?)
## 3. The core loop
What does the player do over and over? Draw it as a circle:
`Play a round -> earn coins -> upgrade/unlock -> play a harder round`
- Why is it fun the 1st time?
- Why is it still fun the 50th time?
## 4. Controls
| Action | Keyboard | Mobile | Controller |
|---|---|---|---|
| Move | WASD | Thumbstick | Left stick |
| Main action | Click / E | Tap button | RT |
## 5. Progression
- What do players unlock? (levels, items, areas, cosmetics)
- How fast? (first unlock within 2 minutes!)
- What's the long-term goal?
## 6. Content list
| Thing | How many at launch | Later |
|---|---|---|
| Levels / maps | | |
| Items / pets / skins | | |
| Enemies / obstacles | | |
## 7. Social
Friends, trading, leaderboards, versus, co-op, private servers?
## 8. Monetization (fair and clear)
- Game passes (permanent):
- Developer products (consumables):
- Rule: nothing pay-to-win in competitive modes; show odds for any random rewards.
## 9. Art & sound style
3 reference images, a colour palette (see our Palette Pack), the music mood.
## 10. Retention
Daily rewards, quests, events, updates schedule, codes.
## 11. Milestones
| Milestone | What's done | Date |
|---|---|---|
| Prototype | Core loop playable, ugly is fine | |
| Alpha | All systems in, test with friends | |
| Beta | Polish, balance, analytics | |
| Launch | Store page, thumbnails, trailer | |
## 12. Risks
What could go wrong, and what's the backup plan?MORE
