My last level (King of Swing-1) was broken. I guess forgot to finish it before I uploaded it.

Is there a way to update a level and keep the same level code?
No, but I did see that you still have the old version uploaded.
I added a level myself. Actually I took some folks advice and made a remix/extended edition of one of my earlier levels "Underground"
The new level is "Chaos Below!"

I made the level longer. All power-ups are stackable. I added a checkpoint and... I hope ya'll enjoy the shooter section. spac316 the shooter part was inspired by Super Mario Land AND by your most recent Michael Bay level update!
Give it a try and leave me some feedback.
