I'm not playing for the best time (the best time was 3.17, other runs were sometimes slower, sometimes closer). I'm sure someone managed to last up to 10 minutes. It's more about what it takes.
The visuals are stunning. The effects are excellent. The sound is good. The animation is smooth.
My personal opinion: I would remove the walls; the character disappears into them (especially from below). As an example, imagine there's no visual limitation on the platform from which you can fall (we're somewhere in the air; there are no walls).
But YES, it's a really good, addictive game that keeps you hooked time after time. Where time without action is not your friend.
