i really like this! i hope that you add more islands in the future with more complicated placement constraints or different themes. maybe magic/mana can be an additional currency in more advanced levels. perhaps add a card bank so players can view cards they've unlocked and figure out synergies more easily. it's unclear to me if certain buildings are locked behind other purchases, or certain "paths" i should follow in the shop. i like the free placement of buildings and how close you can zoom in. i'm also unclear if there's a penalty for destroying buildings or if its purely net positive for added space. overall its awesome, i'd enjoy both more content and clarity
