Emerald Eater

My first attempt at DragonRuby and my entry for TeenyTiny DragonRuby MiniGameJam Collect the emeralds. Avoid the red bumpers. Each emerald is worth 1 point. Dont be too slow every 10 seconds, the bumpers are cleared but 4 points are deducted. WASD / Arrow keys - moveESC - pauseENTER - restart
