The crash when entering the shed a second time no longer occurs. Though you may want to have Sal respond differently when looking at items in the shed, especially the bug poison because it's something that could conceivably be used to get rid of Jack.
A new bug I did find in hour 4 is that when Sal clicks on the fallen tree he still gives Jack's response of "I allready got the axe..." before giving his own. Also if Jack didn't all ready take the spray paint from the shed then Sal can swipe it when he enters it.
The zombie is much more evil looking then the green skeleton, Good job with that!
If you let Gordy hang though Jack still refers to The zombie as a skeleton "The skeleton had strung him up on a rope and left him to die."
Perhaps when Jack runs from the zombie when it shows up to claim Gordy Jack can issue some sort of comment when leaving the room or going back in the house so you know he chickened out?
Good to see the problem with giving Darcy the salt and candle have been fixed
Also see that you fixed the problem with giving the star to the ghost before finding out about his pot, but it looks like the topic for police stills shows up early.
You may want to make Astrid check both the cabinet AND the fridge in hour 5 and also have Astrid change into her raincoat before following Jack outside in hour 7.
Also when entering the shed when it's dark in chapter 6 onward you may wish to allow the lighted area to move about the room if that can be done.
Don't think the bit with fighting/running from the wolves needs to be any harder, though a skip button of some sort to bypass the scene would be nice, or maybe allow the player to continue even if the wolves did get him?
