Pretty fun. I got the long-range Healing Bolt & the Mana Ward as my first two spells, so for the late game I would sit in a warded spot & lob healing as villagers spawned in. Got out right after reaching level 9, with 35~ deaths.
I do wish there was a way to make villagers stop spawning in, but still let you protect the ones on-screen. Maybe a church bell in the village that you can ring?
Also, Mana Wards can be placed during the day & remain during that night. I only noticed this on my final night, and didn't make too much use of it, but figured you should know.
