Gamification Design

Create a design concept for the gamification of the learning process in the app.

Things to consider:
- [ ] Integrate into current app or create a new one
- [ ] What are the game mechanics?
- [ ] What can be learned whilst playing?
- [ ] Is it fun? (important!)
- [ ] Leveling system?
- [ ] Rewards (e.g. Coupons from industry partners)?

No file, test, or entry point is named. Review the current RecyclingApp before deciding whether gamification belongs in the existing app or a new one, then define the mechanics, learning outcomes, fun factor, leveling, and rewards. Done means a documented gamification design concept addressing each consideration.
