Zombie Defense (itch) (Dzeruo)

Id like some suggestions if you could to try and make it more fun. New maps, enemies and defenses are already coming, but feel free to tell me what youd like. A graphical overhaul is also due to come, but fear not, I pretend to keep the style simple as I feel thats the better way to go for this type of game. Unfortunatly there is still no linux/mac port seeing as the game is so early in its development stages.
