This was such a calming, relaxing experience. At first, my only complaint was going to be the camera positioning, but then I realized that you could turn it with E. I still think that the areas under the clouds could be play-tested a bit more to make sure you can see stuff underneath them well.
I also wish there was some kind of "yay you did it" moment when you make all the bridges so that way you know that the game is pretty much over. I kinda wandered for a bit like "is there anything else?" but the world was so calming to be in that I didn't really mind.
Other than that, I really had a great time playing this. Your 3-D world is nice and crisp without too many busy elements that would clog up your design, and the music is so calming. It's fun to play these kinds of exploration-type games, and they must be so hard to pull off for a jam!
