To start off, I love the art and animation of the game. It's very atmospheric and it tells a story without "telling a story". The boss was pretty cool and had a smooth feel to it.
The gameplay was...painful at times. You have to watch your ammo super closely or you literally can't finish the game, even the knife uses ammo. When you walk through a door you have a 50/50 chance of being instantly killed. Some parts feel like pure luck to get through.
All that said, with a few tweaks it would be a great game. Those are just my opinions. It was a fun experience.
