Personally, I liked the test project.
I've read the description of the game, which is pretty short, but the part where you talk about how "siren head is dead" kind of got to me. I don't think any character is dead just because there was that one time and people used to make a huge amount of games about the character. Of course, sometimes it gets annoying, but if you truly believe that your game is different, you should never stop on the projects just because of a bias towards a certain topic.
What I'm trying to say is that the game has a potential. The sound design, atmosphere and the menu effects were neat. I would love to see the full version, at least 10-15 minutes of gameplay with some texts to read or a chase. Don't give up on the project unless you don't want to commit from the start - advice from a not so great game developer like me.
Best of luck with the future projects. Cheers!
