This is an impressively clever take on the theme, using a loop of death and rebirth to create a chaotic tower defense-esque game is very inspired. It's not especially difficult, but I think that's to the game's advantage, especially considering that a final victory condition does exist. So you can kinda just mindlessly watch your zombie army grow and consume all, which feels great because of how spot on the game feel is. I do have an issue with the controls tho, with the sorts of motions that the game expects my hand to make. Moving with WASD and doing actions with space and R resulted in my hand making this really awkward almost crab shape which really started to hurt my wrist as the game got more hectic. I wonder if consuming corpses could've been a right click thing, and picking them up and placing them down could've been a left click input. That way your left arm isn't doing the entire brunt of the game's interaction.
Other than that though I do need to stress once again that this is a stellar entry!
