It's not bad, not at all.
That being said, it's not always clear how to progress. I just beat Mavis, and have gone a few days and... No clue what to do now.
Thank you.
After beating her, you should be able to transform Mabel into a magical girl so that she will help you in the forest, but that's pretty much the end of the content for now.
I will try to add the Task system on the Phone menu for the next version, so that players will be able to see if there's something missing or not.
