Gameplay and Critique ;)
Many thanks for this really nice review! I couldn't have explained the core elements of the game better myself!
And yes, I completely understand your criticism regarding the defense and offense upgrades not being "moveable." I’ve thought a lot about this topic, but in the end, I decided against allowing replacements, as that would make the gameplay even more micro-intensive.
I also have to agree with you that the game is missing a bit of a story element. I think I just got too caught up in the game design and ended up overlooking that part a little.
