I got up to like 20k points before with my students (i dont remember the exact amount, that might be too high) but i was really killing it one day. I got a fucking backwards highway in Kansas, no joke. There was like a shack.
My rules for my class and friends is that youre NOT ALLOWED to move the arrow more than twice. This allows you to see languages which is a huge giveaway and not fair.
Play it the Professional way. Dont move the camera!
