I know it is just a minor detail but sometimes even though the shapes fit right, the game thinks it is not finished yet. It happened a few times now, when I let go of the mouse while moving, so the shape moves a bit further from the point I released the mouse and fits. I guess release point does not match the criteria, so I have to move a piece apart and put again. It may confuse the player. :)
I think you have a nice puzzle game if you juice it up a bit. I strongly recommend http://www.gdcvault.com/play/1016487/Juice-It-or-Lose
Best. :)
I think this is a great effort and a nice game. Couple of notes:
I loved your idea of shaking the screen to emphasize a moment but it is way too frequent and after a while it just loses its meaning and becomes that thing in the game that annoys you.
I get that the game is based on the story, (duh) but the initial dialogue set (before the murder) is a bit too long. I think you can cut the initial dialogues to have an impressive game-opener.
Hope to see more. :)
