Cheats for Irisu Syndrome! (PC)
Instantly Unlock Metsu Mode: To instantly unlock Metsu Mode without making the 40,000-point milestone, go to the title screen and press on your arrow keys Up, Up, Up, Up, Right, Right, Down. A sound will confirm correct entry: in about 5 seconds, a cat will appear at the lower-right corner. Click it to enter Metsu mode. Note: This is not recommended for new players as it skips a large segment of the story.
