First, play the game until you are ready. Then, press the up arrow. Press spacebar until it is done. After you go through the stages of mitosis click next. Play the match game. Then click done...and you are done!
It is a lot of different blocks for all the different levels. The catch game is made like the tutorial one but I changed the sprites. Then I just used a lot of "when this sprite clicked" and "when backdrop switches to ...". There were like, 8 NEXT buttons. it was pretty simple in the end. I thought it would be a lot harder. (No i didn't).
