Hi Dobsy,
Sorry for the late response. We had a small vacation for a bit.
Thank you for the feedback!
We are currently making updates to make the best experience possible. Some of the things you mentioned will be featured in the product version.
Regarding the tutorials, we have a more in depth guide on the player controls in the full version.
Good catch on the narration not syncing correctly! We are trying to have them match up as best as possible.
