How did you get out of the circle? I have no way of testing that since I'm not actually good enough to get out of the circle... You should just die when you get out of it. Leaving the circle is not a goal!!!!
I've found a fix for the -1 problem, don't type in -1. Joking. Honestly, I'll try to fix that soon, but I'm really busy, so for now, don't type in negative numbers.
