Hello Admins!
Some changes to how save resets work. If you want to reset your save file completely press backspace on your keyboard while the game is active. A prompt will show up and pressing backspace again will reset your save file.
It should be noted that this option is for a clean slate and under most circumstances would not be required for regular play. If you wish to try a different evolutionary line for your PiMon you can do so with the "Soft Reset" button instead!
