Don't worry, it's JUST possible to get past those presses. Just DON'T STOP HOLDING THE LEFT ARROW KEY and you'll be fine. They land almost exactly behind you.

I wouldn't make something impossible now would I? Wait, yes I would, never mind. But this isn't. I've tested all that I have so far myself, with minimal use of testing shortcuts like skipping rooms. Minimal use, I say!
As for plotline... well, technically I guess it's after the events of CS... here, the opening cutscene runs like this.
Curly: There's the teleporter!
Curly: We'd better get back home before that storm hits.
Cutly: Uh-oh, the rain's already started.
She teleports home (it looks a bit awkward since I don't believe there's an ANP for Curly teleporting) but when you head toward the teleporter it gets struck by lightning. Just your luck, it's broken, and you'll have to "take the long way home."
But like I said, that's just me having fun

I really don't know what the story is. You go through all the levels in the same order... you get the same weapons and whatnot...
Eh, well let's just say the objective is to get a good time.
Not sure about how I'm going to do that, for that matter. Though highly condensed, it'll still take probably up to ten minutes to go from start of Graveyard to end of Grasstown... and the Nikumaru Counter does not allow saving. I know I'm going to include something that lets you just try each level individually, but I don't know if I should make that something you have to complete the game first to get, or include it at the beginning, and have the full game in sequence just be a challenge.
That's why I'm not sure what to name it. There IS no point other than "shoot lots of enemies, and do it quickly." Population Xplosion is not a bad idea though... it's true, after all
