Can't wait for KH4, though all I'd be able to do is read about it.
That aside, I decided the Entrance of the Xenoa: Lunar Shadow version should use a different tileset, so I'm currently trying to think something up that'll be fitting for it. Maybe a tileset from a past mod I worked on, I dunno.
My main memory of the original version which was Jenka Nightmare Revived by Slither that was like, an ending to the original.
I don't remember half of it, I just know it happens after Quote got knocked out around the end of the game.
And it was like a stupid thing where after getting the booster 2.0, you went through rooms that had a similar level design, with spikes that grew larger in wideness as you went through doors, only to come at the end where you meet a Droll looking character that says he's one of those Omega or Alpha things I forgot, then you have a little boss fight, then Misery comes in and it's the end. I discovered later that this was not the good ending, it was like an alternate one but instead of going upward, I went somewhere else. It was a long way back to do the other ending so I ended it here.
I have the same opinion as ZarroTsu expressed in the boss rush room in his version, it was a bit underwhelming. The mod aged pretty poorly even if it was pretty advanced compared to some of it's time, it did get the soul of Cave Story and I believe it was fairly judged back then. Nowadays, it's pretty meh, a lot of quirk of the level design would be outrageous and or just suck. The story is good for a sequel, and it was pretty advanced and innovative. It's mainly it's legacy that is uphold, I wouldn't recommend it nowadays.
ZarroTsu fixed things, exaggerated others but, having played this version long looong ago, I can't really say much on it. I just remember having a good time.
(Edit:The beginning is slow af though and it doesn't pick up the pace until you hear about teleporters and destroy the two bosses, so a quarter of the game is slow and boring.)
