I ended up unable to cross what I think was the bridge (the challenge after the green bog) and I'm not sure why. Was it my dead corpse in the way? I restarted twice and it happened both times. I also didn't quite get why the first death in the green bog created a boat. Is it meant to make a boat every time I die? If I want to cross a bridge do I use a boat? That was my thought process trying to infer the rules of the game and figure out how to succeed. When I read the description about corpses stacking and helping you advance it sounded cool, there's a good idea in that, that's the game I want to play.
