Aside from the basic stats, players have the ability to earn 'feats', which are special skills or abilities. These feats come in two general varieties, known as Basic Feats and Fun Feats. The basic feats are those which most directly affect gameplay and a player character's ability to survive in the game. Fun feats are more geared towards affecting the player's experience while playing the game, often as restrictions in transformation (e.g. Male Preferred) or the character's mental state (e.g. Kinky). As many ending scenarios are affected by the player's gender, these can unlock otherwise difficult or impossible to obtain endings to enrich the play experience, but often have little effect on the 'game' itself. The main exception to this last part are the 'gender preferred' feats, which may locks players out from receiving some content, because of a gender requirement, or access content they'd otherwise not be able to see (gender-specific variations).
At the start of the game, a player is granted 1 basic feat and 1 fun feat with which to start. Many feats have requirements to be met before they can be taken, so not all will be available at any given time. Every three levels, the player is granted a slot for another basic feat, which can be obtained by volunteering with Dr Matt. These can be gotten at any time by visiting him at his lab, or can be saved until desired. Fun feats are gained automatically every five levels. To skip gaining one, press ESC.
