I'm newbie in C2.
The existing comments do not explain much.
But, it does not report usage details, because it was used.
It's not easy for a beginner to understand everything,
so you need to comment in detail.
Did not comment on the event sheet: "finalscreensheet"
The event sheet: "finalscreensheet" line 11 is empty, has some reason?
I did not understand the Global Variable: "AcceptableCharacters" and because it is at the bottom of the page?
Did not rename all sprites.
You do not inform if a local variable exists.
I'll have to test and study more to understand.
I do not regret buying (I'not repentant of purchase)
But I was annoyed that you did not take care of all the details.
