Thank you so much for the thoughtful reply. I'm happy that you like the game and see its huge potential.
That's a good idea to indicate monster's dietary needs - the feeding system + sleeping for next day will come at [0.0.3] and I'll definitely add that to the monster's profile.
As for monsters AI behavior - right now we only have the most basic patrol/wander behavior, after v0.1 release we'll definitely improve monsters AI :)
