This save file is meant to replace the save file in C:\Users[USERNAME]\AppData\LocalLow\Thomas K_ Young\Dadish 3D\SavesDir (or presumably the similar file in the mobile version). BACKUP YOUR ORIGINAL VERSION OF THIS FILE FOR SAFETY.

WARNING: THIS WILL RESET YOUR PBs IN GAME. It will also turn off sound, music, and vibration and also invert y-axis control. You can very easily return these settings to normal in game using the menus. I tried to prevent this from happening by editing other parts of this save file, but it didn't work and I am too lazy to fix that.

All that I did to make this save file was edit the file in notepad and changed the "stars_got200111111101111111110111111111011111111101111111110" to ""stars_got200000000000000000000000000000000000000000000000000" (1's meaning the star was found, 0's meaning no star found. also first 2 levels and boss fights don't have stars). If you want to do this manually you can, or you can use the file I uploaded here.

This file will, hopefully, become obsolete once the dev fixes the game so that timer mode automatically resets the stars of each level. I already contacted them via twitter about this, so don't spam the dev please.
