1. Time Attack. Once you click on Normal/Simple, the Time Attack mode starts.
Beat the clock at a consitent rank of 110 (default).
2. Rank Game.
Also avialable on Normal/simple after having played Select-Mode.
The rank constantly increases, until you got hit.
The Scoreboard is splitted up into 2 charts as seen here:

Rules: Only default option scores are allowed.
Make sure, to take a screenshot when your time is at least 100 seconds (Time Attack Mode), or reached a rank of at least 90 (Rank Mode).
