High ratings from me the visuals and theme blend really well with the gameplay. I really enjoyed this game! The first thing that came to mind was Metal Gear.
The only thing I didn’t like is that the sensors can see you through obstacles. It pulls me out of the sneaky experience when they can detect you even with something between you and them. Also, a short pause after the drones explode would help,I died multiple times because I started moving while the camera was still adjusting.
But overall, great job on the level design! :D
