Well basically I just wanted to prevent save-scumming in the game. That's why saving is so difficult in the game. With an auto-save system people could just quit the game the second they think things take a wrong turn and then continue with the auto-save. Games like Dark Souls give you a penalty if you quit the game suddenly without going through the menu, but frankly I don't know how to make a proper system like that :P
Another big reason was to encourage starting the game over rather than trying to get everything in one run. And finally, save books are heaven's gift now in the game. Everybody wants them and I think it's a nice rush when you see yourself getting one.
I tried to make the game so that you can still play it through in bite-sized portions if you know what you are doing. Still I understand the frustration, because I play games in short intervals too because of real life stuff.
And yeah, proofreading sounds good! I already got some testers notifying me on typos, but if you find any please let me know! English is not my native language so there are surely a lot of mistakes here and there. If you use Discord, I think that would be the best place for that.
