Awesome atmosphere !
The way you start the misson from a vantage point where you can get to scout a bit what the map looks like to plan how you’re gonna take down the towers is really cool :D
Also the whole concept of the player being a Vampire hitman is an awesome mix, especially with how much agility you give with the limited flight ability, the health system with the remaining blood mist is also really clever, both as a mechanic, and as a tie in to the game’s premise.
And i digged the little details like the MGS style inication of the guards’s status with the exclamation mark or question mark when they search. and the “Howl alert” when they notice one’s been shot.
Had a great time playing this, this would be a really cool if you expanded upon it to make a full game out of it :)
