I removed that 512, it was a debugging value. The path is now correctly determined.

No need to set local_path to an attribute of the game class, regardless, it technically works, I guess? =D Thank you, merging!

[johanneskool]

That way I don't have to redefine it in write_score(), or can that be done another way?

[CRImier]

Usually, you can just add it at the top of the file, globally, so that other classes can use it.
