The point is to avoid dying against more powerful enemies and having to start all over again.
Obviously that's the point for buffing up player health or damage or whatever all they are doing. The question was, "What is the purpose of the
demo?" Is it not to showcase gameplay mechanics? How can you properly display that when you've stacked the deck unnaturally in favor of the player character? If I have to make a million assumptions about how the game is
actually going to play when things aren't rigged in my favor, what exactly has this preview
previewed?
You're better off just describing the mechanics and the numbers if you're not going to give me an accurate picture of how things actually work.
