Loved the game! felt very polished and even though text based games aren't usually my thing I still really enjoyed it.
It also definitely took some actual thinking on my end. and I loved the mechanic of choosing the right part of the brain. I liked the sound design as well but definitely could use a bit of mixing and rebalancing.
A nice QOL change you could add is being able to see what options each part of the brain gives you before you lock your choice in.
