I finished it in like one day and then slept on the hard floor of my neighbor's room. Super mid, short and simple, yet I somehow remember pretty much everything of this game, even though it's been more than ten years since I've played it. Odd.
Man, some of the color combinations really mess with my red-green color blindness lol.
The platforming mechanics are really solid here: nice weighty movement and a fantastic wall jump. The color system impacts both platforming and combat and feels engaging.
