This is a really interesting concept, and a good use of the theme. I would be curious to see how this could be expanded upon with more time, but it seems to me this has the basis of a solid arcade game. The camera really needs to be zoomed out though. It's so cramped you can't really plan where you're going to walk next. Also, the boomerang behaves more like I would expect a flail to behave than a boomerang. You might consider taking some inspiration from the legend of zelda and having it chase you rather than just slingshot towards the center. Alternativly, you could just change it from a boomerang to a ball and chain, problem solved. This is a great jam game, and I'm really interested in this concept. Well done!
