Fix Bug: 'ReferenceError: starColor is not defined' in or related to this line: 'var particle = self.attachAsset('star', {' Line Number: 10
User prompt
make sure start particles have the same color asthe previously destroyed star
User prompt
start particle effect should have the same color as the start that is destroyed
User prompt
random star colors should be very bright
User prompt
stars should be painted with random colors
User prompt
add scale effect to start during the game. it should increase and decreases its size all the time
User prompt
make star scale update on tick
User prompt
star should increase and decresase its size all the time.
User prompt
when dot is destroyed wait for 2 seconds before game over
User prompt
add a new particle effect for when the dot is destroyed
User prompt
