Currently, our Leaderboard is fairly simple, you will be ranked by the highest score you get in-game. You can see your rank and the player around you.
The UI of Leaderboard needs to be polished in the future and maybe there are some bugs need to be fixed.
I will include the fix and enhancements in future updates. This game is still under development in his early stages. I will do my best.
Your understanding and patience are greatly appreciated.
