super interesting way of implementing narrative choices! i liked how "upgrading" your stats means more holes in the brain that you can use rather than a direct numerical upgrade; i wonder if being able to choose between that and the standard stat increase would be an interesting thing to play with. i think just a little more initial clarity with the tutorial would help, and as someone else already mentioned it'd be nice if all your choices progressed or punished you instead of being stuck in a "loop" until you select the right option.
overall a really cool game! all the elements worked really well together ✨
