Awesome game! Played until I beat it, I was a bit confused on the parts and what they did at first. I thought I needed the collectors which took a lot of money and left no defense but then I realized the ore machines gave you the metals. Also I didn't realize at first you had to click to unlock but eventually figured it out. Great use of the space and lots of fun weapons and enemies. The visuals are polished and cohesive which made it stand out to me.
