- Improve the soul gauge to fill properly. The algorithm is different for each difficulty.

The scores would take a lot of space if stored as readable objects so they are stored compressed. If you need to edit your scores, you can do so by opening dev console and entering `scoreStorage.get()`. Expand to the song and double click on values that you need to edit. When you are done editing, do not forget to save your scores with `scoreStorage.save()`. Adding new scores can be done with `scoreStorage.add`, first get a template with `obj=scoreStorage.template(),obj` and after editing, add it with `scoreStorage.add("song name", "oni", obj)`. To remove a score use `scoreStorage.remove("song name"[, "oni"])`.
