Great game overall! The mechanics work very well and are pretty fun and original. You managed to have a well-rounded experience with some complexity and micro-management without it feeling that complicated. The graphics and the music fit perfectly with the type of game (plus the chicken sounds got me good). Some side notes, having 3 fields felt a bit too much, I could only really manage to take care of 2. Also, while it was serviceable, the water nozzle felt a bit weak, I think it would've been even better if it worked like a grenade launcher, with a slower fire rate, but launching big bubbles of water.
One of my favorites so far, great job :D
