Day 13 was a big one with a bunch of animations complete as well as a major bit of coding, the Save System.
I put a ton of thought into the save system to be able to save multiple different games and access them separately through a list on the menu screen. This keep track of all the basic items such as player position and health as well as manages which cutscenes the player has completed.
I also have a very simple way to add save points / check points anywhere on the map in only seconds. It all works seamlessly.
