I quite didn't understand the game at first and struggled to understand what the blue thing was doing. Kinda underwhelming when I finished it. It looks like it could be better though, the buttons just need to be more visually appealing. I had to find out how to click and place the things, I pressed the turrets on the store a ton of times before realizing I had selected it and had to click on somewhere to place it. There was literally nothing indicating I had selected it. So visual feedback and maybe sound feedback is what's lacking the most imo.
Work on those things and overall ig it has some potential. The limitation looks unused though :(
