In his 1.5 September release, VAULTMAN admitted he cut a lot of the content out of the game when he ported it over. This was to test out the new interfaces (maps, menus, etc) and fix the bugs that would be present. He's also recreating the story a bit with more choice options that impact the playthrough. Claims he has help.
He said the content would return in the next version. I assume that is 2.0, as 1.6 was a mess. Set to hit April 1st.. praying it's not a joke. He's shelfed his other project to work on this which is inspiring.
VAULTMAN is on very thin ice IMO. His patrons (myself formerly included) have been very critical of him for a long time. If he blows the 2.0 release, you'd have to think his support is going to crash and burn.
