The main inspiration, however, came from the works of cyberpunk writers, and especially Rudy Rucker. The simplest situation is the player facing an enemy, and both have a set of platforms to move on, and they try to defeat each other by shooting these ZNRG bolts that can rebound off the walls. Another possible situation that comes to my mind is in a level, where you have to shoot at a series of ZNRG accumulators to create a ZNRG flow, like an electric line, leading to a finale, huge weapon that will let you defeat the level-boss. In another level, you are in a labyrinth of teleporting platforms, and you have to find your way out by pressing the right buttons to activate and deactivate the right teleports. The environments are so different and varied that they are a reason of interest for themselves.
Every opponent is different, in fact.
Moreover, when facing the same kind of enemy twice, differences in the environment can radically change your game style. Other enemies can only be destroyed through the use of secondary weapons, which are a precious resource throughout the game. An example of a secondary weapon is a mine that goes on a platform and stays there until an enemy jumps there, when it explodes. To shoot your secondary weapon, you must keep the fire button pressed while steady. Keep the left button pressed to use a secondary weapon or to perform a faster shot.
