Part II: Implicit disappearance of the variable

wFrameCounter is playing Hide & Seek

First, thank you for the tutorial. :smile:

**Description:** While translating the tutorial into French, I noticed something: wFrameCounter is only used in Lesson 15: Objects, and it's never used afterwards. For example, if I follow the tutorial and try to match the line numbers when editing main.asm, we should end up with this source code in Lesson 17: Input [main.asm file](https://pastebin.com/dQmUZW3r).

**Solution:** One way to fix this minor issue could be to remove all content related to the counter and explain why we don't need it after Lesson 15: Objects. Another approach would be to reimplement it if it's meaningful.
