In the twine version I keep on getting an error where it says "LocalStorage quota exceeded" but my storage on my device is fine. What is the problem?
Besides the other replies, it's important to know that Chromium based browsers (Chrome, Edge, Vivaldi, etc.) share the limited storage space between all web pages. So if you play a few html games the storage is full quickly. As mentioned it just around 10MB, some games can fill that up fast (Free Cities).
Firefox based browser keep the storage for websites separately, so the 10MB limit goes for each website without interfering with each other. So if you have trouble with no space and don't want to delete save games, then I recommend switching to a Firefox based browser.
