3rd paragraph

I believe the correct last phrase of the paragraphe should be: "When you're testing this feature, set fleet_drop_speed to a higher value..." and not "set alien_drop_speed to a higher value".

I could not find "_alien_drop_speed" parameter in the code (either mine or the online available official corrections), but "fleet_drop_speed" does exist and work fine for this purpose.

2nd paragraph

At the top of the page, in the first paragraph explaining changes to do to alien_invasion.py file, I believe the two following lines:
"
# Decrement ships left.
self.stats.ships_left -= 1
"
should be marked in bold characters since, though text is identical, they need to be reindented after adding a new condition for the instruction to be properly performed.
