Summarise your game!
Take the role of a big f. gun. Buy upgrades and shoot at your enemies. After you fire each shot you control the shell to ensure it hits exactly where you want. Gameplay in 2 parts. The first part is where you upgrade the gun and select what enemy camp to shoot at. The second part is where you control the shell and aim it toward the group of enemies you want to hit. Based on how many and what type of enemies you destroyed you get resources for the next day.

Please explain how your game fits the theme:
You are a big gun so technically you are a weapon
