Hmm. Ok. That's really not how version numbering works though. And itch.io's installer/manager/updater app can't handle something that strange. It wants to install 0.18, but can be forced to install 0.14, but not both side-by-side. Dev: This would work much better as a Part 1 and Part 2 as separate applications; or a main game, and a part 2 defined as a DLC for it. The installer could deal with that if it's set up right.
