Siginificant update today with some QOL stuff and internal changes as well as a fix for level 1-6.
Changes include:

• Added new confirmation message/method for making a new file.
  
• Fixed S-Rank kill requirement on 1-6 to be physically possible (meaning you can actually p-rank it now)
  
• Added badges to the secondary menu to mark progress on individual chapters. The first appears for having beat all the main sequence levels in a chapter. The second appears for P-Ranking all main sequence levels in the chapter. The third appears for 100% completing the chapter.
  
• Significant internal progress on chapter 2.
