Great this better than all the other crab games! The animation is a nice touch too, you might want to consider making levels with each level they could add a lobster or something...

OK, well to start with as mentioned in the description this only a background, when you have the start button in the background it will not be able to do anything as it is not an Actor merely an image. I recommend the video tutorials or check out some source code from games similar to yours for help. Have fun making your game
