There are a few things needed to get your cut-in and sprites to work.
Your directory paths were a bit off, and you forgot to load the graphics for the cut-in.
These are necessary to include in your code, among the other things already there..
...
let CSD = GetCurrentScriptDirectory;
let imgBoss = CSD ~ "Patchouli Knowledge Sprite.png";
let BossCutIn = CSD ~ "Patchouli Knowledge.png";
...
@Initialize {
LoadGraphic(BossCutIn);
LoadGraphic(imgBoss);
SetTexture(imgBoss);
SetGraphicRect(0, 0, 63, 63);
CutIn(YOUMU,"Sun Sign"\""Suncross Bullet Festival"\",BossCutIn,0,0,200,600);
}
Also, 300 seconds of play-time is too much for the carrot laser script. The idea is good and the execution works, but the length is a bit excessive. :V
