Awesome gameplay, but the level layout is a bit frustrating. Especially when you're having a really fluid run and getting close to the 5000m badge.
"Okay, doing good, damn a bomb. Ok just nail this jump CRAP the building ended, can't jump to the next!!! *slams wall* FFFFFFFFF" or "Ok, gotta jump to the next building, WTF?! I was supposed to nail that window? How was I supposed to see that when I had to jump? FFFFF"
