It took quite a while, but it's finally out. Fully free, no ads, no in-app purchases (besides a "Support the developer" option), no data collection and fully offline playable. All you need is your phone and GPS :)
I originally made the game to go on walks, unfortunately I sat even more in front of my PC to develop it. It is what it is. Hopefully it motivates some of you to get your steps in π
General idea of the game: Collect ingredients, brew them into potions and sell them to merchants. With the gold and reputation you get you can buy things and decorate your neighborhood. Other players see the same map and resources (so you can indirectly play together), but the game world fully belongs to you (singleplayer only).
General roadmap right now:
Adding achievements
Adding buildings you can improve over time (tavern to attract merchants and an ingredient tree you need to grow)
More minigames and improving the existing ones
And of course bugfixes, please let me know if you run into issues :)
For any questions and suggestions I'm always available!
I have tried it. So far, I had to open the Google Maps app while the app is open so it will exit "Waiting for GPS." Maybe for it to trigger the location service. Also, I think the map will be friendlier if it can be rotated based on the compass or manual rotation by pinch. The current setup would be fine only if you are already familiar with the roads in the area. But, for a free app, I like that there is an alternative i can use for Pokemon Go or Ingress.
