I've been playing this game on endless mode and 3 times now, my raft has just gotten stuck in positions that I can't do anything about. For example, once I went to a camp that was way off to the side in like a little cove area. When I tried to leave, I absolutely could not get my raft back into the flow of the river. I had to just run into the wall over and over until I drowned. Just now, the river split into 2 separate paths and I guess I chose the wrong one. It was completely blocked by rocks and I couldn't get back out. Is this just a normal part of the game? It seems like a very stupid thing to have to deal with. I've never been able to make it far enough to get a motor upgrade, maybe that would help? It still sucks when you're having a good run and it ends so unexpectedly due to something totally out of your control.
