Credits are hard limited to 1.000.000.000. Did anything special occur while playing or was it just that easy?

Everything goes normal but i found it strange because despite the 4 players, one gave up early and another was a begginer, so, me and iman00b were playing an game for four.. And after a while (when towers were full upgraded) it was very easy to hold without loosing lifes

I´m on another Coop Survival (Big Combo Easy) and this seems that will never ends.. Round 330 and still goes.. Creeps reach about the same place..

It seems that after some rounds, creeps difficult won´t increase, am i right?
