To move the jellyfish up press the up arrow on your device, to go down click the down arrow on your device to go right the right arrow in your device and finally if you want to go left press the left arrow on your keyboard. NEW UPDATE: Star has become smiley face which has 2 faces 1 masculine 1 feminine... Becomes feminine when left arrow pressed or becomes masculine again when 8 key pressed.
Something that you might not expect is that this is my first game on scratch on my laptop the others I made on my tablet and iPad. It does not matter also if you are playing this on a device which does not include a keyboard then you can also just wait and the star will come to you. This is a fun game which you can also see code as it's a tutorial too.
