So you wanna make an attack? Its harder than the original one. There are 9 more blocks but 1 isnt working, there are 9 boxes! dont use box size 9, its the flybone of boxes. the 2 new souls are orange varients, one makes you jump, the other has you move. like an orange attack in on the soul, simple concept. use change heart to find them. change song with backdrop and sprites with sans. use box reset to fix blue mode bugs, use angle reset to fix bone bugs. The attack is in ATTACK sprite at the very top left. Now get to it!
