- This is a bug which I've fixed, but haven't released the update for (was waiting to see if anything else cropped up, but only knew of it happening to 1 other person so far - funnily enough Edmundito! But I'll release the update, which should work without breaking saves.
If you haven't already used the rope on the chair, that should fix it (the bug is with using any inv other than the rope on the chair) or in the updated version a) it shouldn't happen to start with b) using any inv item on the chair will fix it if Molly's baseline is messed up previously)
Hose: That's fine, some items can be used for more than one thing!

- I didn't set anything as the escape key, as that can be used to skip cutscenes and didn't want someone doing that accidentally while trying to open a menu. F1 - Options, F5 - Save, F7 - Load as handily demonstrated here (but not anywhere in game yet)
Two Mollies is because of the previous baseline / walkbehind bug, because the interface actually uses characters for a little scaling trick. Once the baseline is solved, you should only see one molly
