The visuals in this game are so beautiful it's truly incredible. It gives the game a very unique style that I can't help but be truly impressed by. The music also complements it well and gives it this ethereal / dreamy feel that is truly spectacular.
If you wanted to improve, adding checkpoints would be nice. It was also hard to tell where I could and could not walk, especially in the beginning jumping area. Increasing the player speed could also make the game feel a little better.
Overall cool game!
