I played on a U360 mapped to 4 way. I've played other games with it, but this one, with all the short turns in the maze, made me remap it a bit with a bigger center dead zone and smaller diagonal transition regions to avoid a lot of misturns I was making. By the end it was working well.
On a side note, thanks to everyone who posted. This was a hard game and I was pretty happy with the score I got after putting in a lot of time on it, until I saw I was in dead last. As the rules state, it's great to see everyone's scores, even if they're not first or second, to know what the range is, and maybe compare notes with other people around the same level. It can also give a feasible goal to reach.
