I'm on the leaderboard!
The sense of speed is so good in this. I found that even when I had plenty of time to react early in the game I felt like I was hurtling along, and it only improved as I travelled further :)
The slight horizontal travel of the carts added an extra layer of difficulty that worked really well. Also appreciated that obstacles would knock you back rather than instant killing you - still tricky, but much more forgiving and feels much better to play.
Great game :)
