The control is a bit unique but also a bit imprecise. I've hazy memories that it was like that even when relatively new. So sometimes I press down but it goes diagonal, It is almost like the frustration of a virtual d-pad on a touch screen but with an actual physical control button/pad. Without that issue though this game would be too easy and simply so it actually is a positive/feature on this game. The whole video is a single try, all "levels"/"mazes" completed once then most a second cycle. Each cycle until down to a 30 count start the timer is supposed to decrease by 5 and each cycle adds a hole to the maze. 14 cycles/rounds total according to the instructions. Supposedly after round 4 there are "invisible walls" which is a misnomer since they are described as actually walls you can pass through.
