Well, I recently played Little Falls, and found all the endings (A-F). Since I couldn’t find a walkthrough, I’ll post a small heads-up here, with your permission of course, Emily.
SPOILERS AHEAD —- SPOILERS AHEAD
To get the best ending: Get the knife from your wife, hide behind the steel-clad door, attack, go in the basement, get the gun.
The game also has a bug in one of it’s endings. You can kill Sonja with the knife, yet she’ll still attack you if you try to lock the house door.
