I personally like the tutorial as it is now. It instructs the basics of every part of the game clearly and doesn't spoil in full detail about the other clouds. A bonus could be videos showing the instructed parts? For example, a brief basic video of what is a good way to setup movement with the seeds.
There seems to be a potential bug. If you go to the last instructed part, go back a step, you can't go forward through the instructions again until you start the game again.
