So cute! Also, love the parallax effect! One thing I did notice though is that I think the windows are meant to raise the alarm level like the guards do? But there's no effect when you walk past them. Well done!
To be honest, the windows were added as a decorative elements, however if they did raise the detection slightly, that would make the Player's pathing be far more interesting as they assess whether to take the detection, or go for a longer path! Good shout!
