Análisis de la app Look Out! Monsters! para 19 de mayo

Look Out! Monsters! is a fast paced math game where the object is to score 10 points before losing all your energy. Your monster is Harry. You control the direction that Harry moves by tapping the arrows. Repeatedly tapping the same arrow makes Harry move faster. The object is to move Harry to the target where the correct answer is shown. Tapping Go! starts the game, but before you begin use the slider to select a math skill. While playing the game carefully watch Harry's energy level. It it gets too low the game will be over. Remember: Correct answers increase Harry's energy.
