Can you make cheap money on girlsense

i usually play bad hair day and there is a cheat on More Bloons. When you get to level 3 aim for the top right bloon. when the congrats message pops up press ok. DO NOT CLICK NEXT OR REPLAY LEVEL. click reset level even thought the rainbow is still there, you can still hit the top right bloon, and you can keep doing that until you have enough cash. :)
