every new run you have to delete the save file so i thought it be easier to just make a batch file that deletes the save and runs the game. open up notepad then enter this on the first line.

del "C:\Users\ENTER_USER_HERE\AppData\LocalLow\Pillowdrift\Stellar Swing\¤.wifsav"

replace the ENTER_USER_HERE with your user, the file location might differ for you so double check. now on a new line enter

start "" "C:\stellarswing-windows\stellarswing.exe"

change the C:\stellarswing-windows\stellarswing.exe with wherever you have the game located. final save then name the file and choose the location to whatever you please but make the extension .bat then choose the location to save it.

To make things more linear, one can use the system variable %userprofile% to automatically point towards "C:\Users\ENTER_USER_HERE".

..and then create a shortcut to that batch file (and eventually add some custom icon to it or something).
