• Horizontally looping world - later used in Defender and SMB2

• ​Confusing but creative layout (tilted view ground movement on outdoors screens however if in Superman form you move north or south you end up in on another screen - used as a shortcut feature apparently, when entering a building there's no exit on the same screen - instead you go d/l/r for a few screens to exit and these play out in top down view - a subway system apparently and you change stops by exiting a screen upwards)

• No save or map feature

• Object interaction (pick up and carry+drop NPCs and some objects)

• Transform (from clark kent into superman via the phone booth, only use for this is that you need to turn back into clark kent after capturing the criminals and enter the daily planet building as him to complete the game)

• Scripted event (enemies blowing up the bridge)

• "X-ray" vision ability (start with it) - lets you view adjacent screens by holding in that direction (kinda like the binoculars in Metal Gear)

• Chopper enemy that acts like the bat in Adventure (can carry any object it flies into) - can't be destroyed

• The moving cryptonite satellites poison you (can't fly nor carry objects) and you have to touch lois lane to restore your powers

• Difficulty options (affects enemy speed and how easily lois lane shows up when poisoned)

• Can't die - later used in Wario Land 2

• ​Pause feature

• ​"Criminals left" counter in the GUI

• ​Keeps track of your time but there is no time limit (it's there to gauge how quickly you beat the game)
