I'm Continuing to like the game, I think I found a weird specific bug though. I recently bought the steam version and I noticed it continued off some of my previous progress from the itch version. (Either that or the steam demo, but I don't think so) I started at around day 22ish, and I continued progressing until day 30. I didn't know how to solve the puzzle for day 30 so I looked at the hint and it said to use the slime extract. But in my inventory I don't have the slime! I think the weird mismatch of version data caused me to not have the slime or something. I've found a work around though I'm just replaying every day since you first receive the slime extract. For example I'm on day 22 and I have the slime. I can't go to day 23 because when I open it I no longer have the slime extract. But if I play and finish day 22 I will have the slime extract for day 23. I've been repeating these steps going up the days. I thought I'd try to give you as detailed an error report as possible. Thank you. :)
How the save system works is it remembers the items you ended “yesterday” with. So you did exactly the right thing: you got the jar back and played the days, pulling the jar forward until it was needed. Not sure what would have caused your jar to vanish, but I’ll put in some emergency code to respawn it just in case for future players. Thank you for pointing this out!
