About the drawing references, there was an old lovecraftian game, Shadow of the Comet, that simply stole every portrait from famous actors and gotta away with it.
Thank you all for your feedback we appreciate it very much:-)

I know what you mean. But... The thing is that we are not "afraid" of not being commercially successful, but we want our game to be free purposly. I know it's a good thing to make some money, but if we wanted to do that we would have thought about this in the very beginning. And since we have wanted it to be free game from the beginning, we stuck to that form.
About voices: we would love to implement this feature in the future, as a "Deluxe version" but this is whole another project.
