Wow very creative take on the theme, I think the really challenging part of this kind of game for a jam is the balancing. The concept is really strong but right now the balancing of point gain vs progression feels slightly out of tune. I managed to get like 10k+ points with 1 turret and a couple upgrades which let me skip a whole lot of progression i probably wasn't supposed to haha.I think this concept is pretty fun and hope you continue building this out after the jam!
