Like deleting your save you mean? For now you can’t (well you can within the browser console if you really want to) I can implement a "Reset save" button if you want. But can you tell me why do you want to reset everything please?
Yes, to replay it. I really liked it and wanted to replay it to see how fast I can beat it. I don't know how to reset it via console so i just used a different browser, haha
Not at all the case for me, but i guess it could also help if there's ever a specific bug that halts progress. But once again not the case for me!
