Hmm interesting game. I managed to fall over 5000 meters twice but I did not even get a pop-up in-game about the medal, so I assume the medal description is wrong given that other users seem to get the medal.
The platforms are not centered. Sometimes it requires you to get to the other side and back and it can take too long. I waited on the edge until I saw somewhere to land so I did not scroll through the descendsion too fast. The progression in meters does not tell you how far you have fallen but rather how much time has passed. Think of it this way: When you lose because you did not get to the other side and back in time you would have a higher score because you played for a longer time.
It would also be nice to see our score more exactly. The last two digits are hidden by the gradiend and there are no statistics for your last or best run.
