Lagging? Pings are all over the place, green usually, yellow sometimes.
No, I've run this on several wifis including those that test up to 50 MBPS down/5 MBPS up. I've run it on two different chromebooks, many wifi nets, different character types.

I got a 1.25 combo bonus yesterday with 25% faster run and could beat people with that. So, give chromebooks (how would PL know?, in the download, I guess) 5 or 10% speedup and the 25% which is too much.
