Thank you for playing and for your feedback! With 3 washing machines you can focus just to cleanse the third one keeping the first and second at very low RPM (the curse will increase but they will not be damaged). The third washing machine is the fastest to cleanse and to take damage, so it's your priority. Then you can handle the other 2 together. With this tips and if you get good power ups in shop, consumables are not extremely necessary.
Thank you again for playing it
