Really cool game. Love the presentation, the visuals, the small indicators, the scene transitions. The puzzles are good and my only complaint with them is that there aren't more of them. Also good use of the theme.
One other issue is that you can just spam the lasers to keep them in place. One suggestion I have is maybe have an item that you put down to make them focus, like food or something, and when it is used up they lose interest and you only have a limited number of these items before you try for lasers. Or put some cooldown on lasers.
Either way I enjoyed playing your game.
