Aw thanks Rakudajin that's really kind of you to say.
Hm yeah, we introduced night as a reprieve for the player early on, to break up the chaos. Then later we introduce Drogs with torch helmets to start breaking that reprieve. Originally we thought we'd add more of a trap-setting mechanic where you could add more traps at night, but it turned out we enjoyed the possession mechanic so much that we focused all our time on that part instead.
Thanks for playing!
