i cant do both the id tag, and the good ending. and cuz of the code resets everytime u reset, its impossible. whenever i do the good ending, i buy things and spend points on da shop which means i cant buy the id tag. what am i supposed to do

It's possible, because I did it several times to ensure that it's real to achieve

If you can't do it, try buying Hi-tech blender in Ms.LemonS. It will help you a lot!
