Tile World file location help (Linux)

[Flexico]

I installed the "tworld" package with APT, but it stores some files in "~/.tworld" like I would expect, but others (level sets and resource files) in "/usr/share/games/tworld". I would like everything to be in "~/.tworld", and I read somewhere in the documentation that I can specify different folders, but I can't find how to actually do it. Help please?
