Traceurs IIG 15

This achievement to me was a little difficult to get. While you're in the dungeon, you have to clear boards to open up a bunch of boards below you. I'm currently down to 50 on an avg now but some people have gotten this achievement with 26 floors open. I think it's luck depending on the layout of the dungeon you're going down that day or pure luck on hitting the button fast enough.

Once you've cleared down a good ways into the dungeon, you use your D-pad's up or down button, depending if you're on the top or bottom for where you're starting, and hit it repeatedly as fast as you can. This will make your guy jump over boards instead of going one by one up/down them. You have to jump 5 at one time to unlock the achievement.

Something you might try if you're having trouble like me is to not use your finger to hit as fast as you can but use the controller to hit your finger. You can hold your finger, thumb or which ever finger you want over the D-pad button you're using but with your other hand, use it to shake the controller against your finger. If you're missing your finger, hold 2 fingers together together over the button so it won't miss. You can probably hit it faster this way unless you're just really good at fast button pressing.
