This is me experimenting in 1.6 with changing the number in the character change item, to be 1 higher, than bass. In 1.6, this changed the character from Mega Man into Mega Man, but as I predicted, this was the number for roll (the next number, making sense). And as I knew from the trailer / prerelease videos that roll falls down 1 tiles, you can beat it normally in 1.7, and for 1.6, it's a zip only orb. Thus making this probably the first level with 1.7 content in it, made pre 1.7
