The music built up pretty nicely, but it ended sort of abruptly. It would me much better if extended a bit.
Very nice, I like the tone you set right from the beginning, it really pulls you in, but I also feel like it's a tease since it's only a minute- I think it'd be awesome if it was longer and really built on the ideas that you started. But for an opening scene or a trailer it would fit well since something it wouldn't need to be super long and would be the part of the game that just teases you anyway before you really get into the story itself.
Seems more fitting in a promotional trailer for an adventure game where it pans across the landscape then cuts to lots of different scenes showing off the gameplay to end with the title across the screen. Wonderful job.
Please contact me if you would like to use this in a project. We can discuss the details.
