What’s the difference between normal, hard, and hardcore mode in Another World: 20th Anniversary Edition?

The 20th anniversary edition of Another World has three difficulty levels:

  • Normal Mode
  • Hard Mode
  • Hardcore Mode

What’s the difference between each difficulty level?


The following answer has been provided by zabeus from this comment:

So far I've found differences in the number of checkpoints, and the length of time that energy shields last. Hard difficulty should be identical to the original game.
