The tower defence idea comes across clearly, with zombies walking the winding path toward the house while the map shifts between day and night. The pumpkin shop and the 30 sc starting money gave me a clear plan to try, even if I struggled to get a tower placed. My constructive note is that placing a tower needs a clearer step, since clicking the pumpkin and then a tile did not place one for me, so a short placement hint would help a lot.
