Figured it'd be good to have these made. I made practice save files for each split in the game with the current 2 8bac route. For each split with an 8bac in it, I also made a save right before the 8bac so it can be practiced specifically.

To use a save, extract it to the game's save location (see https://www.pcgamingwiki.com/wiki/Fez#Save_game_data_location for the location on your operating system) and rename it to just "SaveSlotN" where N is from 0-2, then load it in game.
