This looks good so far. I tried the demo version some time ago, and it was indeed most enjoyable.
Here's my two cents on your intro video (based, of course, on the youtube video- I don't know how much it's changed since). It's a little rambley, but raises a couple of points on the use of camera:
I think the very first "video" in the game- your intro- should play itself, without forcing the player to interact just to make it flow. Once you get to the actual game and dialogue becomes a bit longer and interaction is naturally expected, yeah. But for your intro, you might want to consider timing that first speech bubble as opposed to having the player press spacebar.
The zoom out following that, I assume uses curvevalue? It would probably be more effective if the camera got faster as it moved away (as opposed to suddenly jerking itself away), before then using curvevalue to smoothly stop it at the end. Maybe rotating the camera backwards a little along the x-axis, so you're looking up at the tower, emphasising it's height, would further enhance the impression.
Following that, the camera flows to the base of the tower. The movement of the camera doesn't seem necessary there, and it would be more effective to simply jump to that spot. Perhaps accompany that with another gradual, very short distance zoom-out and a slight pan around the base (rotate along the y a little). If you decide to look up to the tower in the previous shot, then looking down a little at the base would compliment nicely here.
Again, next shot, the use of curvevalue is a bit obvious. Perhaps a spin around the tower, camera staring almost straight down, as it ascends, as opposed to the current setup.
The shot from the top of the tower is good. Perhaps round it off with the camera getting ahead of itself, diving down to the water's surface, before jumping to the next shot.
Next shot, seems good. You've already fixed the early speech bubble, so that should be fine.
Perhaps, as the tower nears the end of it's descent, you should begin to slowly pan out, as oppose to sweeping suddenly away at the end.
Last shot at the water is great. I noticed, however, that you can see the upper part of the menu when the camera travels to the title. I assume this is intentional?

I've attached what is essentially my annotations in diagram form, just to help explain my thoughts in a less long winded fashion.
Good luck be with you sir.
Give me an ounce of irony, good apothecary, to sweeten my imagination.
