Press the green flag several times < and > to move space to throw ninja star ^ to fly yellow dots give you a mouse-aimable attack that goes through everything kill the gray cat to complete the level red kills you shurikenbending lol in levels with duplicates you have to kill the real cat
Movement engine is a suggestion for the Air studio (http://scratch.mit.edu/studios/631368/projects/) For some reason, level 15 is unbeatable. Sorry about that. I'm working on it. Due to technical difficulties, I've no choice but to completely redo level 15. OKAY, apparently level 15 is like sprite glue, so, at least for now, I give up.
