I agree that it's definitely on the easier end for a medium badge, and I did consider making it an easy badge, but I think it's just barely out of easy badge range in terms of length and a couple of the puzzle difficulties (not that any are really all that hard, but easy badges are generally even easier).
i always get these huge lag spikes in the game and when they happen, I fall through things, even the whole map sometimes. I'm going for the hard badge which is making this much harder because I just got a time of 182.73 and I would have definitely gotten under 180 if I hadnt fell through the map..
Thanks! (:
