Cool concept. Took a little to figure out how to manipulate enemies and the world but the game was simple enough to just experiment and have fun. I did accidentally cause my browser to go back a couple times because of right clicking and dragging but that is just a web issue.
One thing that took me way too long to realize is I could shoot multiple times to pull a target to another point. Having some way to indicate that as a option probably would help.
Had lots of fun playing around with what I could do. Great job.
