A nice idea and a clever use of ren'py to boot! I like the idea of part of the escape relying on another character whose state isn't immediately apparent to you. There's a lot of potential in something like that, though I don't feel like it got utilized to its fullest extent.
I've got three notable critiques, all of which should be fairly easy to rectify with a little iteration.
First, I like the art direction you chose, but it suffered from real readabiltiy issues. It's fine if everything's moody and greyscale, but when the player doesn't know what parts of the room they can and can't click on it quickly becomes a random spammy clickfest until something happens. Like the opposite of pixel hunting. Some kind of feedback when my mouse is hovering over something important wouldn't have gone amiss.
Second, I found the progression a little hard to follow. Things happened quickly, sometimes without explanation, and I feel like a lot of the narrative elements could have used a little more time to breathe. It's ultimately fine if we never find out what our beef with Kim is or why we've been jigsaw'd, but just spending a little more time on the how and why on the present action of the game would have gone a long way.
These two issues were fed by the third one, namely arbitrary progression. Or at least what appeared like arbitrary progression. Why does clicking on the closet do nothing at first, but then give me things later? It's okay for this to be the case, but it needs motivation, otherwise we're back to random clicks.
Don't mistake my critiques for me not liking it, I actually did! I've always enjoyed these games and you did a respectable job of putting one together in 48 hours from scratch. There's potential here with a little more polish and care, and I hope you can make something great out it!
