Name: Pi Runner
Description: Pi Runner A character continuously runs forward in an infinite runner-style game, collecting or dodging Pi coins along the way.
I've created Pi Runner, a mobile-first infinite runner game with the following features:
The game is fully playable on mobile devices with intuitive touch controls. The character automatically runs forward, and players simply tap to jump over obstacles or reach higher coins. The difficulty gradually increases as the game speed ramps up, creating an engaging infinite runner experience!
I've reduced the player's movement speed in Pi Runner from 2x to 1x to improve playability and pacing:
The game now starts at a more comfortable 1x speed, making it easier for players to get into the rhythm before the difficulty gradually ramps up!
