After

After #14 done, we need to rewrite how to save the player data.
We need to store the file into %AppData% for Windows environment and ~/.SuperMarioBros.3 for Linux environment because before the save.json is stored into res of game code source and we don't have the possibility to had different save between computer or between user (It do to delete the save.json into res, not really user friendly)
As the MapsGenerator, maybe the json format is to heavy.

inventory=null,null,null
position=16,128
...

Had a text file is better to fast read.

Render save.json to oriented object

• inventory.py
• state.py
• position.py
• save.py
