Hey, thanks for the kind words - I'm glad you're enjoying the game, and hope you stick with it to the end! :)
As for your questions:
1. All saves are automatically transferred between each new version - you don't have to do anything. Just don't ever delete the game if you're on Android or you'll lose all your saves! (Deleting it on Win, Mac & Linux is fine)
2. The singular "yourself" is correct and yes... yes I am ;) I'm actually a lot better about taking care of myself than I was at first, though, and I do take one week off every two-plus months.
3. I DO have a shady game company backing me up! Sadly, it's my own shady game company and I'm the only employee... but still, it has a kinda-creepy logo! So I think it counts.
Hope that answers your questions! :)
