This game is weird, put it mildy. I just defeated a sewer crab boss and next room is all ice. It has 3 glaciers which I can easily avoid but no matter where I walk and I walked everywhere in that room last 2 hours I hit some invisible force and ground breaks, reseting the room and I have start over. I also cant get back up to beginning parts of sewer. There is no analog control like walking slow on snow so you either move(fast run animation) or you just sit in one place.
