Jevilishly difficult hidden bosses.
And...

Further chapters... you must buy.
Is Chapter 5 the last chapter?
Nope! The story is still continuing, and more Chapters will be added for free over time.

Don,t forget
Absolutely butifull game, played mostly/ entirely on the steam deck and played perfectly. I understand most key story points but I tend to get lost in other bits. All 8 chapters I've played so far have been amazing, can't believe Frisk was the Night's original vessel before it was trashed. If people don't like this game it's probably because of there lack off JARONA
holy shi its soo good omg omg
