1. use the walkthrough 1.9 mega linked in op - page 1guys I have one question I played this game a long long time ago and I dont remember shit about the story (well I do remember some bits) but one thing I remember is that you do a lot of walking now my question is, can I miss content if I dont use the wt? or its easy to follow the whore route without missing any scene? cause the last wt is for the 1.7/9 and the last version of the game is 2.0 oh and any idea if someone will do a 4k upscale of the renders in this game? other games have got that treatment already
2. you can of course play without the walkthrough, but it helps to look at it every now and then since there are several hidden scenes and prerequisites choices that Lily has to make to trigger the various paths and future scenes. Choices matter and if you make the wrong choice once you can miss a lot. Besides, it's also fun to try different paths to see different scenes - it's not always obvious which one is the best path. The guide, while not perfect (and out dated), will help you make better informed choices.
The step from v1.9 to 2.0 does not really require a guide so walkthrough v1.9 will do. hope that helps.
