This is a really interesting project, and I'd like to see what you can add on to this! I love the feeling of flying and being free to explore the world, so this game really resonated with me.
Some feedback:
- Maybe add a cloud layer under the islands as well as random clouds around the sky so the player has a good point of reference while flying. It was hard to tell I was even moving sometimes.
- On a related note, the islands feel a bit far apart sometimes.
- Audio would really elevate this experience.
- Maybe add a post processing effect around the borders of the screen (a radial blur is really good for this) to simulate the wind in your face.
- I'd like to have something to do in this world. It's a really good foundation for a variety of genres and I want to see what you can come up with!
