Should have read the description I guess =).
I had 3 attempts each with multiple tries

1.  First time:
   Figuring things out, walk around opening doors. Found a black thing, I pressed on it.
   Time passes. I lost? 
   Tried I again same result the number of black things seems to increase... it was 5/8 now its 9/12 (or something like that)
   Thought the invisible parts of the black things where because of the sun.
   Few other attempts... nothing changed
   Think I died once in an attempt
2.  Second time: 
   I watched the video, close blinds... i see. But why?
   Tried closing the blinds. The room goes green when I close them all. I guess I have to clear each room.
   Tried the tiny map, found 2 black things.  now what? mby the game doesn't have an ending?
3.  Third time:
   I read the description.
   Found out that the invisible parts of the black things are because of the lack of sun...
   Completed the tiny map and small map.

I would have liked to have some music on the background in the game or something.
The inverted mouse setting. I didn't really understood why it is not off by default. I am glad there was a setting for it tho. Playing the game with the mouse inverted wouldn't have been pleasant... 

A story introduction inside the game is a necessary addition in the future (or at least I think so). 

Good job! Its a really nice game.

It took me some rounds before I figured out how to play. Got a bit scared when remnant took me. Creative game of using lights, blinds, time and remnants. 

Dude, it's atmospheric, but it's a little boring for me)

Really fun and intuitive game loop and excellent visuals and sound design. All the changes you made in the devlog added to the overall ambiance a lot, especially the visuals of the sun rays shining into the room. I liked having to learn the rules of the world myself without being spoon-fed information on what to do and found the helpful hints after losing to be a great way of bridging the knowledge gap without being too hand-holdy. Very engaging little experience, nice work dev!!

an amazing game, took me a few tries to figure it out but its great.

Had a few jump scares before I realized the Remnant only attacks when all the blinds in a room are closed. Thankfully, that tip was tucked into the menu hints, which I read after losing a bunch.

Lost several games on the medium map, but switching to the tiny map just to see what winning felt like was satisfying. I really appreciate the difficulty options.

The game is awesome. The sound effect of closing the venetian blinds is oddly satisfying, and the controls feel super fluid.

I looked at the video demo of your game and it looks great. Unfortunately, when I downloaded it, my antivirus flagged it. Even if it's a false positive, I hope you can resolve it. I’d play, but I can’t in good conscience until my system gives the all-clear. Or maybe put up a web version?

The game is very beautiful. It's easy to learn and fun to play almost immediately :-)

For what it's worth, I encountered a graphics bug in an (open) window on the ceiling: no light, orange dotted lines.

This game has such a unique gameplay, but it is easy to understand and fun to play at the same time. It took me one or two rounds to completely understand it and after that, shutting windows and doors quickly became addictive. The whole game feels super polished. The light (love the color and the god rays), the ambient background and the empty rooms all come together to create a very strange vibe which is great.

By replacing the "Karen" model in the latest update, you took away the last point I found to criticize :D The new tentacle remnant fits way better and the particles + sound effect feel very satisfying when you remove a remnant. However, I didn’t quite understand what the circular animation at the cursor represents when a remnant is removed. What does it indicate?

The room generation feels very varied and surprisingly natural. Sometimes I encountered very long rooms with just one window, where the god rays would not touch every corner of the room. Can remnants hide in areas not touched by sunlight? In my case, if there was a remnant in the room, it was always close to the window and I got it.

The game already feels complete in its current form, and I don’t think it needs any expansion. It stands well on its own. However If you plan to extend the gameplay, I could image a game mode where you clear multiple consecutive levels (like floors in a skyscraper). When you shut everything you can enter an elevator and go up to the next floor. Each floor could get bigger and introduce new gameplay elements over time.

Love it. I tried it first in another jam. The improvements you made are spot on. "God rays" really enhance the atmosphere.  Also, the texture on the floors helps to  remember where I was... Remnants behind the columns, not a fan :), but I think it's great for the game.  Keep up the good work!
