Cave Story Walkthrough Part 14: The Last Cave(s)

Yeah, there's 2 versions of this cave depending on how well you did during the game:

Last cave
If you failed to save Curly and didn't get the Booster 2.0, you'll find this easier version of the Last Cave. I think this place is easier than I made it out to be in the video, I was just rushing too much because I didn't know how long it would take me to beat the harder version later on when I got to this part, lol!

Last Cave (Hidden)
If you saved Curly and recovered her memory in the plantation, as well as collected the Booster 2.0, you'll come across this harder version of the cave. You better be good with the booster otherwise you'll be here for a very long time. But, you need to come through here to get the best ending of the game.

Enjoy!
