Well, when it comes to features, preferences differ, and it's impossible to meet everyone's tastes. I've got a lot of feedback from people who liked the break away from the classic Ren'py formula, so if you were expecting something like that, the game probably is not for you. What you perceive as time-wasting someone else might enjoy.
As for some of your main points of critique: I acknowledge the autosave feature is something that, again, might not be for anyone, but it's a design choice that also has technical reasons. You can however reload anytime, you can access the conversation log at any point in the game, which is very similar to a rollback function. You can skip almost every dialog, and the game gives you the choice to deactivate the tutorials right before starting the game (there may be one or two essential ones that will still be displayed, but it won't spam you). The "unnecessary" point&click mechanics are part of the storytelling, which you seem to be interested in. I do admit though, that some cutscene animations have a pacing issue, something that should be improved in the next update.
