It destroys any solid tiles it moves over. The sprite uses the green block tile in jyotyu map16. Diagonal directions don't work properly.
Data files:
• /BG_*/*jyotyu*
Sprite fields:
Path ID: value at nybble 10. If you don't have a matching ID, the game will freeze.
Loads from: list at nybble 9: 0=Level start,1=Midway point
Starting node: value at nybble 6-7
Last node behaviour: list at nybble 4: 0=Nothing (keeps shape),1=Falls apart (doesn't keep shape),2=Comes back and forth,3=Skyrockets (keeps shape),4=Falls apart (keeps shape). Game will freeze if N4 mod 8 is 5 or 6.
Length: value at nybble 8
Slower: checkbox at nybble 5 with mask 1
