WASD or arrow keys to move, Keys 'l' & 'k' to switch between styles. l is more optimized as it compresses all coordinates into a single string, but it cannot be used in delete mode, so the game will force the mode to 2. space or click to build
Saving is already pretty much implemented, all you have to do is click see inside, show the 'Tile positions' list, set the render style to 1 and export that list, and if you want to load something, just import that list. the game takes care of it. Another step up the never-ending staircase of progression!
