The rhythm of the game is too fast, often busy drinking water and eating, the items bar need to optimize, drag or take things is not very smooth, especially when the thirsty death, to the items column to get water. The mechanism of the shark is not very good, because it is always there, will not sometimes have, sometimes not. Perhaps should add some, raft defense mechanism. Need the mechanism of fatigue, need to sleep. To the end of the game most of the time in the busy production of rafts, but obviously the game mechanism can not let me peace of mind.
