This reminds me of FLERP in the best way, its a really satisfying core loop that just works! Build, defend, earn, build some more, repeat... There was some really nice polish here with good sound effect choices, sleek and intuitive visual design, and shaders applied on the core and money boosted enemies. For all the tower defence I've played and made, I don't think I've seen a tower that boosts enemy money on kill before. Really fun game!
