There will be three Chapter 6s.

Need to get the key from chapter 6 before we can leave the board.

>like if there's a pattern to where the symbols are placed it's not one that can be identified by looking at it
Here's everything labelled with routes drawn.

Lastly, the schizo map during Jackenstein has multiple paths with cut off entrances and skip sequences between the pictures. Toby could be fucking with us again but these symbols are super on the nose.

Matches up with the nopumpkin map.

Still reckon this map is the key to everything. You'll NEED to do aborted Snowgrave because getting to chapter 4 to go further with it means you've missed the turn into the alternate routes. Chatper 3 gets an extra key on a second playthrough for a reason.

There's a map hidden in the non-tutorial pumpkinless map in the Jackenstein fight. If you add in the level's key and exit then draw lines through it, it makes what appears to be a map of the game's chapter layout, complete with bosses.

Sans won't let you meet him on routes with an unbroken prophecy.

>>713056053
According to a map hidden in the Jackenstein fight (with the items and exit from the stage added in) there's seemingly a way to escape the prophecy entirely in chapter 3 somewhere...but since the stage requires you to get the key THEN get to the exit, it'll probably require you to get the shelter passcodes from Kris somehow then swap to Susie in chapter 3 and run into the shelter before Kris can stop you.
I don't think Kris is keeping the passcodes from you because they're hiding something in there. I think they're SCARED of what's in there, and with damn good reason.

>You cannot place either egg that you find, this one is particularly egregious because the man behind the tree emphasizes how important it is to place them
You'll probably be able to after we get the alternate ending to chapter 3.
