Project Overview
Goal
Create an online store for unique, sustainable chewing gum that supports conscious purchasing decisions — while delivering a fun, interactive shopping experience.
USP
A blend of sustainable products + gamified features (e.g., bubble gum game, “mystery flavor” mode) with nostalgic 90s-inspired visuals.
User Story

As a conscious consumer, I want to purchase sustainable chewing gum in a simple, playful online shop, so that I can discover new flavors, make a positive impact on the environment, and enjoy the process.
Research & Interviews
- Sustainability-focused buyers (20–40 years old)
- Nostalgia-driven shoppers who enjoy retro aesthetics
- Casual buyers motivated by gamified shopping experiences
6 semi-structured interviews

Sustainability needs to be communicated clearly and credibly.
Fast navigation is a priority — no unnecessary steps in checkout.
Gamification boosts engagement but should not disrupt the buying flow.
Personalization (e.g., “mystery flavor” random mode) is well-received.
