Cute little tower defense. I really liked the theme/ narrative here. Maybe its just because garden gnomes are cool. Or maybe its my deeply seeded disdain for the HOA idk. When making a tower defense one of the more important details is stat visibility. Your unit health, the enemy unit help, damage numbers, and unit descriptions. Because the tower defense girlies love to min/max. This game gets away with it fine because its not some deeply complex TD with upgrades and stat trees and all sorts of craziness, but I still would've liked to see some health bars. Echoing Okayh about the sprite layering. Zombies should render over the gnomes. Last bit of criticism, the menu music and the gameplay music mesh well enough, but I think the gameplay music falls short of the theme. Give me something spookier. That's all I've got. Solid work!
