Nightmare Circus/Tweaker

Back to: Nightmare Circus.

The Tweaker is Nightmare Circus' user-accessible debug mode, allowing players precise control over everything from hitboxes, gravity, timing, and nearly every single gameplay variable used in the Mega Drive game's object oriented-like programming. Referred to by the game’s manual and advertising as U PROGRAM technology, and in-game as the Tweaker, the menu is extensively developed and properly labelled, and unlike the majority of debug modes was actually intended for use by players. The manual even details the menu’s control scheme and additionally offers potential ideas for players to alter gameplay, stating “the possibilities are nearly endless.”

Usage

The Tweaker can be unlocked either by completing the main game or by a button combination; if this is done via the latter method, it will not be recognized as being "fully-cleared". Once unlocked, entering a second password expands the Tweaker menu with a level select. Now, accessing the menu while paused during gameplay will display a new list of variables specific to that stage, meaning enemies and obstacles can have their variables adjusted at any time during gameplay itself.

With the game's rushed development cycle and relatively-shallow gameplay, the Tweaker and its abilities are seen as a means to extend Nightmare Circus' replay value by allowing players to creatively experiment with the gameplay structure. In a sense, it allowed players to create rudimentary "rom hacks" with nothing more than their controller; turning up the difficulty, pouring on the enemies, or giving everything a ridiculous palette.

Variables

The Tweaker is only usable with a Six Button Control Pad.
