I'm not anti-tutorial the way some people are, but it should be optional. The only tutorials I really think are dumb are ones that tell you how to move. Almost every game out there uses the same movement keys (for keyboard). It is either arrow keys or WASD and space for jump. Some games allow num pad arrows as well. But that is all. If you have played any game, you know how to move.
As far as this game, I would like the option to skip the first set of challenges and still get the 4 points. I would still end up doing almost all of them, so it is hardly a big deal, though.
The other challenges aren't what I would really call tutorials, at least not if you aren't reading the text. And reading the text is optional, so I don't have a problem with that. I just look at them as challenges that are entirely optional. You don't have to complete any of them being the intro ones. I actually like having the various challenges. They give me something to do if I get bored. I'll agree that some could be changed to things that are more of a challenge, while others that take forever and often can't be completed by the time you want to start over (10 blood moons, or that gold and silver and diamond one), but it is fine with me that the challenges are there.
