BirdFactory

In BirdFactory, strategically place nests to generate birds and worm pits to produce worms (food). Enhance your production with three available upgrades: Worm Cans, Fridges, and Guano Deposits.

I didn't have time to do everything I wanted, so I rushed the end and didn't do a tutorial or include all the desired things, for example: (one object per square, a number of birds per nest, etc.)

The tutorial:
There are 3 important resources: eggs, worms, guano.
Eggs: used to make birds.
Worms: food for the birds.
Guano: money to buy objects.

1: Right-click to place an object.

2: On Windows, left-click to move the view.

3: There are 3 types of birds:
     Pigeon: gives 2 eggs, consumes 1 worm, and gives 1 guano.
     Robin: gives 5 eggs, consumes 3 worms, and gives 1 guano.
     Seagull: gives 1 egg, consumes 4 worms, and gives 4 guano.

4: There are 2 objects to place:
      Nests: nests with the type of bird.
      Worm_pits: generates +2 worms.

5: There are 3 upgrades to place:
      Fridges: gives +5 maximum capacity for eggs.
      Guano_deposits: gives +5 maximum capacity for guano.
      Worm_cans: gives +5 maximum capacity for worms.
