Thank you! Glad you enjoyed it!
Yes the shadows were intentionally put out of place as to make the guesswork and the puzzle harder, especially during the last puzzle where the player was intended to move the light a lot in order to get the solution. But I guess I should have conveyed that information a bit better, and to ease that confusion. Sorry for that!
The missing sound was the biggest regret I could ever had. I just want to find a corner and hide there now.
