@_benui It's a lot of small things but mainly the improvements come from re-writing the architecture properly based on everything I had learned. The initial code I wrote had me in a place where I couldn't really make improvements. I needed to start fresh with all the gained xp.
@_benui Specifically, I fixed up a lot of unnecessary mem allocation, and cleaned up how I render the tiles to be more efficient. Those are two big ones of about 100 changes.
@nymtuber Good question! They use the same place. In the update after this one I'm working on, I'm going to upgrade all the save systems to be more robust. Meaning more save files, more save info, more save file edit control and so on.
