Nice visual, the huge hand with gun has a sort of 3d feeling like sticking out of the game.
I bought all the update, but didn't get to an end, not sure if there is or you need to pass a certain amount of days or kills.
At the beginning I got confused about how to sell the eggs, I couldn't find any option and only after a while I realised that 1 egg could perhaps be $1 and was enough to collect at least 20 of them to get an upgrade.
Perhaps you can add this info in the instructions.
I found a bit strange that I could stay for long time in the barn collecting eggs and nothing happens while days passed through. Was it intended, a bug, or a glitch? If not intended, maybe you can make something happen if you don't go out for the night, maybe stating it clear when it's day and night when inside the barn.
Overall it's a nice little game to play that fits well the theme. Nicely done.
