This is one of the most enjoyable games I've played yet. I like the whole aesthetic, sound, everything worked together. It also fit the game jam theme really well.
The only thing I wondered is why you wouldn't just work to get your partner killed every time. Then you don't have to split the money and they can't turn on you. It wasn't clear if there was a penalty for them just getting killed right away. I also wasn't sure how much health I had - it wasn't easy to tell if I was about to die.
Overall, really well done and a neat take on the theme - great job!
