Cursor * 10
This is a unique game by Yoshio Ishii from NEKOGAMES. Unique because the focus is gameplay innovation, rather than graphics and soundtrack.
The aim of this game is to make it to the 16th level, this happens by clicking on the staircases. This would be as easy as it sounds if there wasn't a time limit! All movements and mouse clicks are captured on each run, so on the next run your previous efforts (ghosts) will automatically take care of the earlier levels.
