Just to clear things up:
The save system issue that existed in v0.04 and earlier has already been fixed. The fix was implemented in v0.05HF (May 24th), and yes, as always, Patreon supporters got it first, because that's how the release cycle works and will always work. That version just went public with the release of v0.06, which (surprise!) also has the fix.
If you're still hanging around waiting for “a version where saves work”, you might want to check the actual update notes or the game version you’re running, because it's already released on f95zone.
Now, just so there's no further confusion, here’s how I usually update the game:
To those who’ve supported or given constructive feedback, thank you. I’m one dev doing all of this solo, and while I can’t please everyone, I do listen and try to improve things every step of the way.
