Phaser.io is a javascript-based desktop and mobile HTML5 game framework. Based on a game template and a simple tutorial, I created this game in 2018 learning how to implement this gaming library and program some simple game physics.
Directions to play: Use the spacebar to jump + the arrow keys to direct the little gamer. Gather all the coins + the red badge to win! Avoid drinking too much poison or you might lose. Good luck!
