This is - by far - the most extraordinary angel I've ever seen. In more ways than one.

What a unique story this is. Especially if you don't really have experience with that. I didn't expect something of this kind when I started. The graphics fit the surreal atmosphere very well. And they create a very unique identity for the game. The music also suits it very well, but you should really go for something royalty-free. Commercial or not, using songs without a licence is a problem.

FISH SLAP Guy has summed up my observations on the technical side quite well, I won't go into that again.

The puzzles are interesting. I had to use trail and error in a couple of places and got stuck at one point. When I used the ladder and still couldn't get up to the window, I thought the game was bugged. Luckily I saw that you replied to a comment here where someone had the same issue.

Great game. I enjoyed the time I spent with it.

A very cute game, the game style and plot are very funny haha, enjoy the process of playing,nice job:)

Fun and cute game. There were funny animations and interactions throughout the game and the art style looked great. Puzzles were not too difficult, but were also hard enough that they required some amount of thought (which is a good thing).

A few pieces of feedback I have: the continue button seemed to have an inconstantly sized collider, and if it was bigger, or if you could always use enter to progress dialog it would work a lot better. Next, I think there should either always be a custom cursor, or never one, or at least make the Windows cursor invisible (put Cursor.visible = false; to do this). Lastly, some of the characters had the same dialog  before and after they were dead which was a bit confusing.

I have no idea what code has to be used.

Spoilers:

 I know that it has something to do with the order of the pillows and their color in comparison with the picture on the screen. But I tried every possible code this could have been interpretated

Really interesting. I really liked the art style and atmosphere. I found a small bug in which the sprite of the character talking and their dialog and name sometimes wouldn't match, which would make the text confusing, but overall good game!

The background music was awesome. Fit in the atmosphere nicely. Liked the rugged style. Great job! 

I'm enjoying the game so far, but I get to the point where I've propped up the ladder and the chair in the second room. I'm not sure if there's a bug preventing me from using them but the character just keeps saying the window is still too high and he needs something propped under the lightbulb.  Am I supposed to be able to move the character?

Let me know because your game is really cool and I want to finish it.

I enjoyed this!  

Strong premise, a protagonist struggling to retain his memory and humanity despite inhumane treatment.  There is a strong theme of disassociation that creates a surreal vibe throughout; the scenes are both absurd, and mundane to a Kafka-esque degree, at the same time.   The puzzles were the best part, challenging but also engaging.  Keep watching after the credits for the true ending.
