Nice game! I like the hiding mechanic to prevent yourself from being detected by the enemies. The stealth factor was neat, but I'm actually glad we had an option to kill the robots because if it was only stealth, it might have been a bit bland but that's just my opinion so good design choice there. Something that might make the game better is if you're only counted as being caught if the robot sees you for like more than half a second or so because right now it seems too sudden when you get caught.
Overall good job on the game, you did great!
