The current walkthrough isn't really usefull anymore, because almost every chapter has something extras, which wasn't there in version 9.5. So some things aren't happening yet, because you need to do something extra's. For example the Hank & Rose at the bar part, first need to give him the screwdriver so he goes to tie up his wife.
I also missed the fixing of the telescope, if you select one of the chapters to start with.
I already played it a long time ago, and didn't want to waste time again with searching everything over and over in the beginning, so I followed the walkthrough. Guess we have to wait for the update.
You are totally right, this game could use some kind of in-game walkthrough, or a quests/todo page, something that summons which things are still to do. (They can complaing about the Genesis Order al they want, the soulstone/anglestone is brilliant)
And the current update was an update ofcourse, but calling this v10, when it didn't add a new chapter, but only added some nice things to the rest. I would have called this a v9.5 as an update to v9.0.
