i may have put like 100 margin and now i cant play the game how do i undo it

It doesnt seem time based, and it doesnt seem space based. So what makes this 4D?

i've exported some games, and i'm able to import them to play them again, but can't find the files in the exports folder. does anyone know where they're stored?

Anybody have any ideas why this is happening, i don't think that the game updated and i already played for 100hours without any problems. Now it crashes on start

Started playing yesterday and I love the game, when I was close to winning the first one, came down to the last four possible blocks with 2 mines: https://i.imgur.com/VlLD4uo.png Basically there 6 possible arrangements of mines and free spaces, and 2 of those were gave the same arrangement of tip numbers (1) around, so in the end had take a chance. And Lost. My frustration is immeasurable, but i persevere....
