Hello, I was playing this game and right now I'm stuck at one part and I don't know what to do. Can you help me please? I have already got mirror and fixed it, but I can't find Octa. I'm playing on version 0.13.0

Do I have to find save somewhere or it should just continue the game after I reopen it? I tested saving yesterday (bought 1st training with 1 cube), closed the game, reopened it, the game showed me intro, but nothing saved (I got my 1 cube again and training wasn't opened). I really like this game, but I still can't understand how to save.  

Is there a way to save progress on PC, because I don't want to start everything over just because I quit the game. The only button I can see is to delete progress which I already have
