sup peeperonis, I'm just coming to say that Crapbug isn't a thing anymore. I know, I know. I'm working on other things, though, so keep your eyes open...I guess. I'm pretty active in the CSMC so you'll probably see more there if you're REALLY curious but hey, that's up to you, dood.
Be safe out there. The world is wild, be wilder.
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.)
