Thanks for the submission! It was a fun little game. I was able to understand the concept pretty intuitively and was able to make turrets pretty quickly as well.
I felt a little rushed to make the new turrets, so I didn't have time to properly sit down and look at my possible options, since I was just making them as fast as possible. Especially since it didn't seem like the bases or barrels mattered, I just made a bunch with whatever type of ammo I had. Maybe adding a break between waves would allow me to think a bit more about my creations.
