Comment 1 for bug 756741

We are aware of this issue and we are researching about ways to minimize the possibility to get stuck.

Currently, this can only be resolved by designing the levels in a way, that make it rather unlikely for Nikki to get stuck.

Because of the physics engine it might not be possible to get totally rid of this problem in the end. This is one of the reasons why the game will feature a checkpoint based restart system in the future.
