[v1.4] On screen controls for mobile devices. Left/right arrow to rotate and up/down to fire for player 1. WASD for player 2. Simple controls - classic game. I've added a shield because well... who in their right mind would enter an asteroid field without one? It drops 5% per hit. You can also fire backwards. Scoring added which varies depending on the size and speed of the asteroid. Stats displayed using djPro's text engine.
