There's been some questions about what's different, which link should be downloaded, etc. So first of all, the ep4 is an older version containing 1 through 4, ep2 is the newer rewrite which includes ep1 and 2.
Obviously you could still play the older version that goes to ep4, but up to ep3 was written by a different writer, and I wrote ep4. I've seen the question of 'why rewrite?' popping up a lot in here as well, and that's probably the biggest reason. The previous writer and I have significantly different styles, and Cell and I agreed that it would be worth making everything consistent. Plus I'm taking the opportunity to add some changes, hopefully for the better, and fix plot holes, especially one in particular, that I think had the story kind of written into a bit of a corner. While I won't go into details, I'm sure some of you can guess what that was.
Now... I personally understand that a rewrite can be a bit frustrating, and I actually really hate rewriting someone elses work too; it becomes difficult to separate their ideas from my own. But I hope you guys can at least give it a chance, even if that means waiting for us to get caught back up to ep 4 or 5. I have read through most, if not all of the comments, and while not everyone's wishes will be granted, I am doing my best to take into consideration what I think is reasonable, from here, steam, and patreon. And to the best of my abilities, create a compelling narrative that as many people as possible can enjoy.
Oh, and on the point of saves... the saves won't be compatible. There's just too much being added that didn't exist in the old version. New choices, new variable, new scenes. Old saves won't work, even once we're caught back up to ep4.
I hope that helps clear some things up, cheers guys.
