Oh my, it was a very intense game!
First of all, I ADORE the artistic direction! The GUI is GORGEOUS, the background too, and the overall reddish, blood-like tone matched the game very well. And yet, yet, we have this stranger, all in blue, like an anomaly, not realising he's entering a space which isn't his.
The story was very dramatic, and yet straight to the point: so rather than surprise, the main quality here is the execution, and I have to say it was done masterfully. The horror felt gradual as we saw the stranger entangling himself more and more in the painter's room, reproaching him for things that will eventually doom him. It felt like the etymological tragedy: the goat's chant, the animal being put on a show of which everyone but it knows the fatal issue.
The voice acting too was very great, and goodness, the sound design, both the use of the flipping page sound effect and the music, was stellar! Finally, the implementation of the point-and-click portion was a very good introduction to the story and to let us know the fatality of this story (just like how at the start of Greek tragedies, a god would go on stage to predict the whole plot).
Congrats to the whole team on a very great piece!
