Floor Slant is the 16th Expert floor in Monkey Ball and Super Monkey Ball, and the 25th Expert stage in Super Monkey Ball Deluxe. It also appears as the 135th Ultimate stage with continues, and the 175th without.
The goal is at the far corner of the board in a tricky position. Because of this, the floor is quite difficult.
With pause buffering, this level can be cleared pretty easily as long as you have proper timing. In order to do so, hold Up+Left as soon as the level starts, then pause between 59:20-59:28, ideally in the middle as 59:25 gives the best results. With the direction still held, change to Up+Right and unpause. You will land safely and bump directly into the goal. Other timings require proper adjustment of your stick position to land properly in the goal.
