The engine handles all writing and reading in the lists and also allows something similar to 2-dimensional arrays.
It breaks down every list entry into into multiple elements and allows you to read and change elements.
A entry suitable for my engine would look something like this:

200;100;Player;Stick;Apple;;

Now my engine would allow you to easily change the stick to a sword for instance.

Here, check it out!
