Truly love this game. It's phenomenal and a love letter to two games I love so much, UFO 50 and picross.
However.... It's WAY too easy to accidentally delete your entire save file. I lost about 50 puzzles and 3 hours of progress by clicking the wrong thing at the title screen starting up the game. Is there any way to put in protection against that? Like maybe profiles or something.... Really gutted as I had made a lot of progress unlocking things and it's all gone now 😮💨
