The newest in the Jay's Adventure series! When you get to the Garmadon battle, he will run left. Lure him to the other side of the planet, where there is a small floating platform. Jump on it, and then stomp on his head!
I know, I know, there are only six levels, but they are hard! I was looking through my trash folder the other day, and I found a glitchy Jay's Adventure platformer. I didn't have the coding skills to fix it back then, so I deleted it. But I fixed it up, and here it is!
