Help! I am stuck at the Zoo stage and cannot progress, because I cannot push the crate. It's hard to describe so I am using this walkthrough from GamesRadar as an illustration of what I mean (http://www.gamesradar.com/cave-walkthrough/?page=10). The issue I am facing is illustrated by the sixth image from the top.
The attached image shows a crate that is slightly to left of middle of the platform. However, in my case, the crate is all the way to the left, against the wall. I did not push the crate, and it was in that position when my character discovered it. There is no way my character can squeeze between the crate and wall, and push it to the right.
Just wanted to check if this is a bug, and is there anything I can do to progress. Thanks!
