I just finished the demo now, and I have to admit it's pretty good. I like how different choices offer a variety of information regarding the suspect pool, but how there are also more than one means of acquiring knowledge regarding individual recurring suspects. Since it's rather late at night for me at the moment, I'll save my deeper investigations for another day, but I am looking forward to listing out all the current clues to factor a guess as to the true murderer. However, I'm definitely taking the options themselves seriously. I'm curious to know exactly how the story changes depending upon the details Elvira chooses to investigate, as this is ultimately a romance game. The obvious assumption would be to focus solely upon your chosen partner to produce the desired ending, but since Elvira is also in charge of solving a mystery, it seems that you have to balance your desires with determining the best means to close the case. A rather delicate line, I fear. Especially since the person you choose can end up being the criminal in question. Which begs the question: will there be bad endings availablein the game, such as one where Elvira possibly gets herself killed and the mystery remains unsolved?
That would be interesting to see.
Anyways, I'll close off my monologue with a praise over both your current and continued effort over this project. Though I personally am not aware of the full mechanics to creating a game, I am aware of the diligence required to simply write a story - especially one with multiple endings. I love the consistency I've seen and hope to be able to expect the same in the full release when it comes. Since your story and plot seem solid, I believe you should expect to see a good number of customers willing to buy your finished project. I'll certainly be making myself among that number.
P.S. - I just wanted to give extra credit for the trailer. When I watched it, I was itching to try the game before it had a chance to finish. Good job and keep up the good work.
