Very nice for a first game!!!
If i could change one thing it would be the actual view threshold of those enemies, the game screams "dont get seen by their lights" like most game do it, but the light has nothing to do with it as soon as u get close to them even from behind they automatically spot you. Put a collider on the light that should do it.
Again, very nice game, didnt manage to get all orbs :P
please rate my game too :)
