excuse me for being clueless, but what is the favorite flavor option?
The flavor is for the color of the bunny/puca encounter
choosing a different flavor will change the color of the bunnygirl that you encounter.
NOTE: each bunny girl color encounter is considered to be a different encounter so if you want to 100% complete the game you must go through each scenario with each of the colored bunnies.
the encounters where they display the colored character model are affected by the color choice. That would include the arena fight and the debt encounters.
What is affected by the additional choices(relevant to people who care about 100% completion or something like that) would be instances of the different colored encounters being just events that TRIGGER the different color displays such as being buttfucked while facedown and riding on the bunny's lap.
example would be any event that triggers buttfucking facedown while cream option is selected would count as a separate event than buttfucking facedown while chocolate option is selected.
Also any event that would trigger when buttfucking facedown when a separate color option is chosen counts towards this.
An example would be going to demon lord tavern that would end in buttfucking from drinking too much and paying with body to recover debt are different encounters that both trigger buttfucking and either can be used to achieve the different colors for different favourite flavor options in terms of completion.
