Act3 v1 is up if you want to continue. There is information in my latest devlog on it and how to skip ahead but if ya cant be bothered this is what you do:
1: Start a new game and choose “not to take the tutorial.”
2: Proceed as usual.
3: Once you reach the Swirling Tree, go back the way you came from but let the jumping deer pass the screen first, it creates a stupid bug otherwise.
4: MR.TV is the guy you need to talk to if you want to go directly into ACT3.
5: When choosing which level to start Act3 Winter at, know that 17 is actually pretty hard, lower levels are even harder.
When I get back to fiddling with act 1 and 2 I might increase the xp on some bosses to make sure a player who goes through the game without the cheating room ends up on an appropriate level.
6: Choose the Begin ACT3 option at the end of the string of choices if you want to be able to progress through the narrative. The other options are for fucking around and testing shit and will break progression in different ways.
One beautiful day it will be possible to transfer save-files from one demo to the next.
