Hero4Planet: Clicker game about trees and endangered animals

A mobile clicker game for Fundacja Zielona Przystań, a Polish charity: players grew a virtual forest and spent what they earned on cards of endangered animals. We designed and built the Flutter game for iOS and Android and its Strapi backend, in two rounds: 2022–2023 and 2024. The game came out, and it is no longer in the stores.

Hero4Planet on three phones, interface in Polish: two trees growing on floating islands with the player's stats, and the collection of endangered-animal cards.

Client: Fundacja Zielona Przystań
Industry: Education and charity
Platforms: iOS and Android
Built with: Flutter, Strapi, Lottie

01 · Business context

The problem

The foundation wanted a game that teaches players about endangered species and raises money for nature at the same time.

It had to be fun first: a simple, colourful game with friendly illustrations that children and adults would want to come back to, with learning about rare animals and plants built into the play.

It also had to earn money while people played, through ads or small purchases, so that the foundation could give it to ecological fundraisers.

The client

Fundacja Zielona Przystań

A Polish charity that supports people across generations. With Hero4Planet, it wanted to reach younger people with a message about nature and endangered species, through something they already enjoy: a game.

What we built

A Flutter game for iOS and Android, in Polish and English, with a Strapi backend and admin panel and a small service that updated the rankings. Three app developers, a backend developer and two UI/UX designers built the first version, and in 2024 we reworked the game with the foundation. These were its most important features.

Tap to grow a forest

Players tapped to plant and grow virtual trees, which produced in-game currency. Boosts and daily rewards helped them earn more.
Cards of endangered animals

Players spent the currency on cards of rare animals. Each card told where the animal lives and what threatens it.
Ads for a good cause

Players could watch a short ad to switch on a boost. The income from the ads was meant for ecological fundraisers.
Leaderboards

Rankings, statistics and achievements showed the best players, and players could share their progress on social media.

What changed

We built a complete game for iOS and Android with its admin panel and reworked it with the foundation in 2024. The game came out; it is no longer in the stores.

Key achievements

A complete game for iOS and Android, with an admin panel in which the foundation could edit the trees, the animal cards and their in-game prices itself.
A child-friendly design with illustrated trees and animals, and high-quality Lottie animations: the two hardest parts of the project.
A second round in 2024: together with the foundation we reworked the game's rules and screens, and added a forest of collected trees and sending cards to other players.
