Props for open sourcing! I love the idea of a turn-based tower defense and I like the implementation you have here with the hotbar/hand of things to place and the board. It feels a bit too easy, though, and could maybe use a resource mechanic to limit how much you can place, fewer refills each turn, or perhaps the board expands and the number of enemies increases? So many options–I’ve watched your repo and hope to see where you take it!
