After seeing many submission of this jam, I found that the random weapon is quite the popular choice, but not many did the great execution of it. Your one is, though, really good! Obviously, it needs some polish, but for a game jam in 48 hours, the game is nice and satisfying.
I wanted to comment on the camera and some other things, but I've seen some people already did that, so let me just tell you that the game indeed has a potential. Keep up with it, and good luck to you!
P.s. I think you should've upgraded the thumbnail. Let it show more of an actual gameplay rather than the simple name. This way, you could've attracted more potential players to test the game!
