I also had an issue with the controls, like everyone else stated. :) I would have been ok with either WASD movement or maybe movement where the character always faces the mouse pointer, but rotating based on the mouse was a bit awkward.
I also tried with the controller, but it was just as awkward, if not more difficult to control.
I loved the music and overall theme of the game. I happen to be a huge fan of the Thief games, which this game might have some inspiration from I would say. ;)
I didn't quite understand how far the guards could see... I'm ok with not having clear cones of vision, but at least some indicator of how hidden I currently am would be good.
I think it's amazing that you found the time to make a tutorial within the bootcamp's timeline! You're definitely much more advanced than me at least. :D
Can't wait to see what you make of this.
