For your first game, the actual shots with the camera over the bridge and such were really good! However, my experience with the game felt a bit dry. With such a beautiful environment in a game, I wanted control over the character to explore it myself or at least feel like I was, but in this case it basically a short movie where I had to hold down the up arrow to keep it playing. If you had full multi-directional control with some areas blocked off, just that addition alone would be a lot more enjoyable.
The game is definitely lacking in gameplay, but for a first game, the aesthetics, camera shots, and overall visuals were really good!
