wll tbh the tutarial was way too rushed as was the whole game I only had 6 days. So you cant drag the sissors you just click on them. Second to use them click F. If you want to cheak how many organs are needed to harvest hold shift it will pull down a bar in the top right after you cut an organ put it in the the plastic bag/trasperant square. Click the bag to drag it in the ice chest to move to the screen with the ice chest hold Q. T is to open/close the ice chest and thats about it you cant get a score higher than B Rank after that just click on the paper and it repeats.
Thats the best explimation I can give.
