Looks interesting, although slightly confusing. Maybe the different weapons can be introduced one by one as the game progresses. I have trouble using them all (or even knowing what they are and what they do.)

Nice start. It would be nice if we were able to see how hungry lobsters are at any moment (how close to starving). Maybe they can change colour when they get very hungry, or have some sort of indicator next to them...

I like it. Hope some more gets added. Has the potential to be really cool. (Ninto: also like your profile image. Wish I had thought of that...)
