Early on in prototyping we discovered an issue where our bounding boxes were too accurate. The shanty houses had a small overhang in their ceiling, and when this was bounded, even though it was quite small, it became a problem for the player. Jumping right up against one of the shanty buildings would have the player smash their head on the lip, and not clear the building.

You can see the small overhang on this shanty. This was stopping players from jumping over the building
During testing we became aware of the issue and as such avoided it as development continued. However, when testing the game with new players, it was very obvious this issue was causing major headaches for newbies. So i had to go into the source file and re bound each shanty building. This was time consuming but the result was a much smoother experience for players.
