There are 4 levels. Try not to touch the red bar or the butterfly or else you lose! Your character is the ball and you can move it left, right, up, or down. If you touch the black hole (portal) you get to go to the next level. When you finish the 4th level, you win the whole game! Have fun playing this!
Also, make sure you follow me in my studio if you haven't done that yet! Here is the link to my studio! https://scratch.mit.edu/studios/26808787/
