Really fun and fresh take on a tower defense! As one who works retail as my day job, also highly relatable lol
Biggest issue I had, was it took a few tries to realize how to place turrets. Initially I thought it was super bugged because since the mouse controlled the camera I thought I had to walk up to the placement areas, not click them. When trying to click, the camera movement made it really hard to control. Once I got used to it, it was pretty straight forward. I'd suggest maybe a "hold right mouse to move camera" type control.
Overall though, I loved the whole 80s vibe and the overall game play once I got it figured out though. Will definitely be playing it some more. If your team chooses to continue development I'll be looking forward to seeing it's progression! :)
