Goat Simulator, as its name suggests, is a simulation game that lets you play as a goat in a small open-world environment. There really isn't an overall goal to the game, as the player is able to do whatever they want within the game.
General Gameplay
Players take control of a game and maneuver him through an open-world environment, where he can interact with objects and other things, such as people or other animals. The goat has a few moves at his disposal, such as being able to headbutt while going forward or kick while going backwards.

In addition to the above, he is also able to lick objects, which entails his tongue to stick to the object in question. While his tongue is attached, the goat is able to tow these objects/people around with him. There are special abilities as well, such as Ragdoll mode
Score/Multiplier
There isn't a general objective to the game, but the player is able to accrue a score by headbutting, licking and kicking objects. For each one they interact with in this manner, their multiplier will increase by one each time. There is a timer underneath the multiplier that will end it once it empties.
Quests
Quests are present in the game, but are nothing more than performing in-game tasks, such as doing a frontflip or getting a certain overall score. They are simply in the game as tasks to do and don't really have a reward for completing them.
Secrets/Collectibles
Hidden in the game's world are plenty of different secrets, as well as golden goat statues that the player can collect. These secrets sometime lead to new abilities, such as one giving the player the ability to spawn NPC goats whenever they want. Collecting the golden statues will unlock new skins for the goat.
