Example.
Stairs with Arrows, is a seemingly hard challenge where one must jump from the very edge of a brick to the next one. It looks daunting for new players, but it is possible to beat many by holding down space and left/right. It is similar to arrow bricks. Although such a task is easy, not many players know of this tactic so new players may rage and/or quit over this if put too close to the beginning of a level. The holding tactic may not work on variants with larger height/width differences. With the new boost package it can be made harder by using the boost since they are stronger than gravity arrows
