This is an interesting entry. The presentation is solid and makes good use of custom assets. The first person perspective battles are well done, with enemies dying in bloody messes that even have some variance with their graphics. There's little details like that which show the effort put into making the game feel immersive.
The music is well used and fitting for the tone of each event. As simple as they were, I liked the 'hallway' and 'ventilation' sections which required player input to move through the 'environment', clever usage of image stretching to simulate movement.
Every skill is useful and there are items which come in handy during a pinch. I actually don't want to spoil my observations because I think discovering these sort of things for yourself is part of the experience.
