You know what, this could really go somewhere! It's nice to see something a bit different, even if it's unfinished and doesn't quite adhere to the rules.
The first thing I did was fall into the water, and got caught by the Eternal Jailer. Realising in my next playthrough one of those floating bodies was my previous guy who didn't make it, I like to imagine all the other bodies are the rest of us jam participants in some kind of asynchronous online multiplayer game.
It's a cool concept, the kind of thing where it's just weird enough to start creating your own ideas of what the hell is going on and justifying why your boat has two massive machine guns attached to it.
The low poly models fit the strange aesthetic perfectly.
Thanks for uploading, and I enjoyed reading the game page description too.
