I've been playing indie horror games since slender came out and Liftwell (at least at this state) is poorly made.
I know dev put their minds and effort, but it just doesn't click for me.
For the improvements, I would add subtitles, try not to layer the words of the characters, add main menu and settings option and mainly fix the reaccuring notes/comments of the character on them.
Not a great material for a indie horror game vid, but still here is my walkthrough.
