I feel like this could be a pretty cool game by the initial look. I'm not at all sure what it's supposed to be though. The thumbnail you have looks like it has more than what I was getting when I opened the game. When I opened the game only the gun appeared, some text saying that it was for the jam and a button saying start; I had no control though so couldn't start.

My suggestion is to always play your game after packaging incase there are any issues with it. What we play in the viewport may not be how the game plays when packaged. This could have just been an issue with that process. 

Edit: After starting the game I do like the look and I like how I can look around to see the stuff I'm shooting at, a score board, and also outside! Made me feel like I was up in the sky. I was unsure what I was supposed to be getting points for: either shooting the chickens or shooting the bread/potato things?
