I don't know if it's just me, but on the web version after completing the first material-getting minigame for Audrey (15 wood), if you visit her place at nighttime, it returns an error. I forgot to screenshot it, but it basically said cannot return null or something similar. Also, are there no saves on the web version? Or is that only after you reach a certain point in the story?
Yes, I understand which bug you are talking about. Thank you for reporting it - we will fix it.
The web version stores its data in the browser's temporary cache; unfortunately, it's impossible to make saves in it. But, after completing it, you will be able to download a save file for the full version to start from the same place.
