Defend against a wave of pigs trying to eat all your harvest!

Select a defender type on the right by clicking on them.
To place them somewhere, simply click at the square where you want them to be.

Scarecrows are cheap but weak.
Tomatos have passive resource production, but pigs devour them in no time.
Wooden puppets are stronger than the scarecrows.
The black blocks have no attack but are cheap and have a decent amount of hitpoints. Also big pigs don't like how they taste ;)
