Hi! The idea is that you should be extremely careful with these enemies, because after they detect you there's not an easy way to avoid them, you need to be patient, careful and observant. There's a way to destroy them all with a single action and the walls give you a hint about what you need to find and what you need to do. It can be a little hard and frustrating but i promise you it' worthy.
Thanks for the input! I'll check your game as soon as i have tine!
