Great writing for a game form that's very well scoped for a jam. The mood sits somewhere between Cultist Simulator and darker Disco Elysium moments, and I really dig it.
One nitpick - the click-and-click-again UI choice for the brain pin really threw me off and I thought my input wasn't working. Some clearer highlighting would've helped; drag-to-place also would've been okay, since that was my first instinct.
