Since the final Mario Maker 2 update, I have been working day and night, sometimes up until 5am to try and make a super world to unleash on the world.
I am pleased to announce, after 1.5 months, I have finally completed a 38 course super world spread out over 8 themed worlds.
The levels start off easy and increase in difficulty as the game goes on.

If anyone is interested here is the code and some screen shots.
