Goal

From Fantastic Wiki

The goal is the area that all goal objects must reach to achieve victory. When a level has multiple goal objects, all must be in the goal at the same time to win. The borders of a goal area do not count for victory conditions. This small detail makes quite a few user-designed levels impossible to defeat, and stresses the importance of testing your levels for possible victory before publishing them. Scroll over these goals to see analysis of the goal design. Obviously these are exaggerations of the issue, but it is an essential part of level making to make sure that all goal objects can fit into the goal at the same time.

This goal is well designed, as the goal circle can easily fit inside the goal, and it can roll in due to the overlapping terrain. This level is actually solvable.

This goal is awfully designed, as the goal doesn't touch the floor, and the goal object is too big to put in it, therefore this level is impossible.
