Hello and welcome!
I still haven't made myself a pretty homepage, but it'll do for now.
IMPORTANT NOTICE:
My Level Explorer for Super Mario Maker 2 app isn't working as it should. The problem is that the api I use for fetching all the data for the app has been down a lot lately. If that doesn't change soon I'll have to take the app down. The developer behind the api hasn't replied to any of my attempts at reaching out either. So at the moment there's not much I can do...
