In this little, surreal game, you are controlling Tom - a "servant of Yahtzee", sent to the town of Reality-on-the-Norm to make an inspection of the local "Yahtzeebrand" general store. The peculiar, MS-Paint graphics, the surreal humor and a lack of an actual ending make the experience of playing Nihilism quite unusual.
The game is controlled with a mouse; similarly to Sam & Max Hit The Road, right-clicking changes the cursor action (Walk to, Look at, Interact with, Talk to). Your inventory, as well as the Save/Load/Quit buttons, are at the bottom of the screen.
