The third installment from Emanuele Feronato: "Here we go with the 3rd step of “Space is Key” HTML5 prototype made using Phaser, tweens and ARCADE physics. In the first step we created the floors and make the player run and jump, then in step 2 we added deadly obstacles to be avoided as well as some level design concepts and now it’s time to show how to make the player die with a particle explosion if the square hits an obstacle."
