Right, but remember people play games to escape, not be stuck with their accidents like in real life
Don't take one opinion as speaking for everyone. There are hundreds upon hundreds of games you can play to "escape" but something like this to me sounds interesting. There is no "proper" way to make a game, there is no "rules".
If your testers/players find game breaking bugs
and they will, fix them. There is nothing else you can do about that. Auto-save or not those bugs will need to be fixed in the testing stage. So don't let that deter you.
Now as someone who has used Auto-Save in a game (Golden Pearl) I had game breaking bugs, I did have save-corruption, and ultimately I ended up having to commission a brand new auto-save script to fix it all. On top of that I DID add extra manual save slots, but it was because they complimented the gameplay.
For my example in good auto-save I'm going to use Heavy Rain. Heavy Rain is a game where if you don't react fast enough or make the right decision the story will continue on but your mistake will affect the outcome. This is the kind of game where going back and undoing your mistakes would taint the experience. Most of all it's a short game, you can beat it in a few hours. It's not a big deal if you mess up.
But if your auto-save doesn't compliment the gameplay, or if it's not fun, then make it optional or remove it.
Heck, maybe make it optional anyway if you think it's appropriate.
