Wir fahren auf der Autobahn
This achievement can only be grabbed in the Autobahn level.
To reach the required spot, simply jump on the moving squares in the first sublevel and continue jumping to the right until you reach the very end of the map. You will die at the end but will also net the achievement.
This achievement can only be grabbed in the Diamonds level.
The required spot is in the first sub level. You need to reach the right end of the diamond. This can be done by not only jumping one square forward on each beat but also jumping one square to the right.
This achievement can only be grabbed in the Spike Cover level.
The required spot is in the third sub level (just before the end). You need to reach the left upper corner of the map. This can be a bit tricky since it involves jumping over the incoming spikes.
