Well done for finishing and submitting what looks like it might be your first game jam entry (your only game on itch.io). I liked the collecting of wood and stone and cutting down trees to make items to repair and defend your house. The zombies really go for it if you try to stop them demolishing the place. I didn't find the biscuit unfortunately, maybe it was too hidden!
I wasn't sure if I had my headphones connected properly and then I tried out the download version as well and I think I'm right in saying there is no audio of any kind. Is that right?
Some sound effects, more juice on the combat (screen shake, death animation, etc.) and a font that isn't the default Godot font, and you've got the beginnings of a nice little game here. Good job and best luck with the jam.
