Have been excited to play this since I first saw it! I've only been able to get up to 2-3 so far but it's very addictive so I don't think I'll be able to put it down for very long lol.
I was surprised at how puzzly it ended up feeling. Trying to route to the tenants without getting pinned in by the zombies was really engaging, especially as the layout of the levels got more intricate. Some of the seemingly obvious decisions have a lot of depth to them also, at some points I would spend a life over a bullet because the respawn gave me a better chance of getting where I was going for fewer resources. That tradeoff felt cool.
It goes without saying, but the presentation is just incredible. The music is gonna be stuck in my head (:
