I’m not planning to add a save feature right now. I’ve played it so many times myself just to test it, so I totally get wanting a save option... I’ll consider looking into it once the game is mostly finished. I know, it’d be really nice to pick up where you left off...!
You can open the save management screen by pressing the F1 key on a keyboard, or by swiping in from the bottom or right edge of the screen toward the center on a smartphone.
There are 30 save slots, so that should be plenty.
