Project scope
The project involved building a real-time application that would allow users to walk around the city and conquer territories. The app had to be engaging, easy to use, and visually appealing. It should work smoothly on all devices, and displaying that many elements on a map is very challenging.

Challenges
PERFORMANCE
Displaying that many elements on a map while keeping the smooth scroll is very challenging.
WALKING DETECTION
Detecting accurately whether the user is currently walking or not proved to be a big challenge.
CLUSTERING
Clustering users' walking paths on into something tangible on a map was a challenge we struggled to solve for a long time.
Solutions
MAPBOX
We ended up using Mapbox and their advanced rendering algorithms to make sure the app runs smoothly on all devices.
