The following rules were implemented:


E FOR EVERYONE
A game about catching butterflies. Can't get more friendlier than that.


RANDOM PLAYING
The game contains randomized butterflies and terrain (consists of tall grass and normal grass).


LAZINESS
The more the player scare away the butterflies the easier it will be next time (with the same butterfly).


BRAINWASHING PROPAGANDA
The player is actually an apple fanboy (look at his shirt!). With the butterflies (that symbolizes "collectibles") the game projects the opinion that apple products are like collectibles.


COLOR SYMBOLISM
The butterflies' behaviour depends on their color.
