I don't know if this was intentional as the game never really specified, but I found some eyes to not rotate to follow the player. The worst part was I couldn't determine which eys would and which wouldn't until I had been taken by the evil eyes. Even then sometimes I had to loose a level a few times just to figure out which eyes rotate and which don't. Aside from that it was relatively enjoyable.

The non-rotating eyes are intentional. And a bit of Trial and error is part of this game.
But I agree it would have been better if they looked different. I’ve added “make non-rotating eyeballs look different” on the TODO list.
