Hello, fellow SMBX people. I made a level here, so have a free level I guess :^)
The Isle of Lava
One of the first levels you'll find in World 4 of my project, The Peach Paradox. The Glass Beach is a beach world that has been affected badly by the time paradox, with the terrain badly scorched and a sea of lava now washing away at the shore. It's not too difficult, but it's still a blast to play.
