Great concept!
Ever since I read you were working on a new project I had been waiting for this! I liked the atmosphere with the grey colors and the music was awesome! And, after giving it a little thought, the puzzles weren't that much difficult to solve.
The only thing that I think needs improvement is the clicking action, sometimes you have to click on a VERY specific place of a thing (and sometimes even around the thing itself) for the text or action to go through, and it makes the controls feel a little bit slow and frustrating, for example I was stuck on the first room with the bed for a very long time, even though I had (---SPOILER---) clicked the lamp area many times. The same goes for the bellman, the "X" to get out of the drawers/letter screens, and the button at the number puzzle, I also wasn't able to read the three letters that were laying on the floor on the room where there's letters falling, so I don't know if I wasn't able to hit the correct spot or you just weren't supposed to be able to read them.
Anyways, I FLIPPED with the end. I knew the car crash was going to be relevant but... WHAAAAAAAAAAAAAAAAAAAAAT!!
I definitely want to play the sequel! Congratulations on your new project and being on front page ;)
